28.12. Reflection subsun is never an easy catch, but some see them for the rest of us. The specimen on the right on 27.12. in Lieto was already the sixth for the sovereign ruler of the field, Matti Helin. Also Paula Mattila took a good standing by grabbing her second reflection subsun the day before in Turku (left image). The vast reflective surface of the sea seems to favor seeing the halo. Reflection from plain ice may also work for it.

26.12. The James Webb telescope, launched yesterday at 2.20 pm, was photographed 6 hours later at the Hankasalmi Observatory. Arto Oksanen published this picture taken at 8:15 pm, showing both the telescope itself (left) and the second phase of the Ariane launch vehicle (right). They are here at about 79,000 kilometers away from us. The final destination of the telescope, at a distance of one and a half million kilometers, will be reached in about a month.

21.12. On the night between Sunday and Monday, northern lights were widely observed in the moon lit sky, with currently 15 sightings in Sky Warden. On the left is Kari Rytilahti's picture of the action in Pelkosenniemi, on the right Jari Ylioja's shot in Haapavesi. Both pictures were taken in the very minutes of the midnight.

17.12. Last winter's PSCs left a lousy show, but now the first ones photographed on the 15th and 16th December promise a better season. In the photo are Thursday's PSCs seen in Kurikka by Marko Myllyniemi.

16.12. A circle associated with a fireball flash has sparked discussion in Sky Warden. The phenomenon is seen Tero Moilanen's camera recording on 6 December in Haukipudas. Suggestions such as a punch hole cloud created by fireball and a single drop or drops in the camera's protective glass have been brought forward. The slight angularity of the hole would appear point at an artifact, not a real phenomenon in the sky.

10.12. The bout of diamond dusts seem to be now on retreat due to warming weather, so let's admire these outdoor light pillars by Marko Haapala in Kempele two days ago. Haapala was on the move for more than six hours from midnight on Wednesday until morning – on foot! The good thing about this was that jogging after the pillars didn’t get to freeze the man at the crispy below -20 C temperatures. Only the focal length adjusment of the lens got rather stiff, Haapala tells.

8.12. Yesterday the weather allowed to admire the composition of three planets and the crescent moon visible in the southern sky after sunset. This picture was taken by Maria Rönni in Pori at 16.48. "In the crisp -17 degree frost, it was nice to watch the stars and planets appear in the sky," Rönni writes. The planets are, from left to right, Jupiter, Saturn and Venus.

7.12. On Independence Day, Lasse Nurminen photographed mirages in Naantali in a brisk -15 C weather. The islands are just over seven kilometers away. The reflections on the ice come from crystal rosettes. Nurminen added a video of their flickering as wind trembled the thin blades.

5.12. On Sunday, December 5, at 5.30 pm, a bright fireball was seen in Southern and Western Finland. Among the 83 sightings received so far are several dashboard camera recordings. Here is a picture of the bolide from the Nyrölä sky camera. The fireball is located near the horizon at 4:30 o'clock position.

4.12. Comet Leonard continues to brighten. Here is Tapio Lahtinen's photo of the comet together with the globular star cluster M13. Lahtinen took the picture with a remote telescope in Spain on the morning of 3 December. The same combo was also photographed by Petri Kuossari in Tervakoski, Janakkala.

3.12. On the moonless nights of the last three months, Erik Pirtala collected light from the dark nebula LBN 569 in the constellation of Cepheus. This is the first observation in Taivaanvahti of this faint target that Pirtala says is rarely photographed. The total exposure time was 29 hours.

1.12 . A bright fireball was seen on Wednesday at 17:06 with 21 observations reported to Skywarden. Three of these are pictures from automatic cameras, here is shown the great shot by Ville Miettinen's camera at Kangaslammi. Many fireballs have been seen in recent days, a one on the evening of 29.11 was reported by 28 observers.

28.11. With temperatures plummeting across the country, diamond dust halos have taken the stage. At the bottom right is a Lunar display in Jämsä, photographed by Jari Luomanen on Friday night. At the top left is a display next day in Ylöjärvi as pictured by Veli-Pekka Soini. Below is a shot by Jani Päiväniemi of light pillars seen during the race in Ruka on the following evening. And at the top right is an earlier 19 Nov. Lunar display in Pelkosenniemi by Tuula Hilli, which seems to contain the very rarely seen Mikkilä arc. 

26.11. 67P/Churyumov-Gerasimenko and C/2021 A1 (Leonard) are the best comets in the sky right now. The the former, seen on the left in Harri Kiiskinen's picture, is now 9 mag, and it is not expected to brighten any further. On the right is Tapio Lahtinen's image of the Leonard, which is about 8 mag now. It should rise to 4 mag or even brighter and can thus be visible to the naked eye.

24.10. Tero Hiekkalinna targeted on 22. November the Elephant's Trunk Nebula, IC 1396A. “I tried to emulate the color world of the Hubble Space Telescope,” says Hiekkalinna. The object, located 2 400 light-years away from us, according to the infrared observations carried out in 2013 is believed to be the birthplace of stars, containing several stars less than 100,000 years old. The exposure in the image is almost 6 hours.

16.11. The latest issue of Zeniitti web magazine 4/2021 tells about the rocket phenomena of early autumn, the Martian moons and their observations, presents the  crater Archimedes with its surroundings and gives forecasts for the December comet Leonard . Photos: Samu Saarinen, Lasse Ekblom, Veikko Mäkelä and Harry Rabb.

19.11. The partial lunar eclipse was successfully seen in some places in northern Finland in the morning. Joni Virtanen's observation in Kokkola shows the penumbral phase just before the beginning of the partial phase. In the picture taken in Muonio, the Moon is clearly eclipsed at the top.

16.11. Two little halo pearls from the last days in Northern Finland. On the right an exceptionally strong surface 22° halo which on the inside is accompanied by the rarer 9° halo. The photo was taken by Thomas Kast in Rovaniemi on 14.11. On the left is a curious split sun pillar photographed by Reija Satokangas on 12.11. in Inari. This appears to be the first time such an "anomaly" has been photographed.

13.11. Modeling of Ursa's fireball team on Thursday 11.11. the fireball is complete, says Stars and Space . The modeling was led by Jaakko Visuri , whose Thursday night's estimate of the fall area "closer to Petroskai" turned out to be correct. In the picture below, the flight path of the song over Russian Karelia. Based on the modeling, space rocks survived from the fireball to the surface. (Photo by Mikko Suominen, Celestia / Stars and Space) 

11.11. A very bright fireball was spotted today at about 4:40 p.m. The phenomenon was visible in an area that stretches southeast from Oulu to the regions of Joensuu and Savonlinna , where it was not cloudy unlike elsewhere in Finland. Janne Laukkanen was recorded in Joensuu for a video of the spectacular fall of a fireball . According to a rough preliminary estimate, the flight has ended roughly in the areas of the eastern border, on either side of the border. (Photo by Janne Laukkanen)

10.11. Minna Kinnunen was ready with her camera and phone when snowgun originated diamond dust birthed a handsome halo display over the Åre sky on Monday. As is always the case in this class of displays, there are also rarities involved, such as the two upper Parry arcs and helic arc. And closest to the sun sits the enigmatic arc of Moilanen, which is a halo exclusive to diamond dusts.

8.11. The forecast is promising some relaxation to the relentless overcast conditions, which comes handy for the observations of 67P/Churyumov-Gerasimenko that is peaking at 9 magnitude right now. The comet visited closest to the Sun five days ago and will be the closest to us at a distance of 61 million kilometers on November 12th. The picture of the comet here was taken by Veli-Pekka Häkkinen last night.

5.11. Despite high clouds interfering, Samuli Vuorinen's take on Harsosumu is a worthy new addition of this object the library 51 other observations in Skywarden. It’s a mosaic of two images that both got 50 minutes of exposure per channel. Vuorinen exposed H-alpha during the past full moon, O-III and S-II during new moon at the turn of the month, which is when he also photographed the galaxy M33.

3.11. Two observations from the turn of the month. On the right, a red morning sun low at the Helsinki horizon on Nov. 2 photographed by Tuomas Salo. On the left, mammatus clouds seen in Turku by Paula Mattila on the morning of the last day of October. Just as the sun turns red only when it is low, so do do mammatus cloud need low sun for their shape to be discerned.

26.10. This year, the diamond dust halo season opened on October 24th with displays in Rovaniemi and Kuusamo. The picture is from Kuusamo, where the setting was much better. "My girlfriend photographed from the co-driver's seat", writes Veli-Pekka Lehtimäki, who upload two photos in Taivaanvahti. He says the road was slippery which made it impossible to stop to take better pictures.

26.10. Panu Pahkamaa has visited the windswept island of Jurmo in four falls in hope of catching the Milky Way. "After all, it is perhaps the best place in Finland to photograph the Milky Way," he writes. On his latest visit in September this year, the weather was finally favourable and Pahkamaa has now published in Taivaanvahti a picture he took on the rocky shore of the island.

25.10. The halo display itself is mundane, but how the picture was taken is significant. This is Finland's first automatic halo camera. The device, realized by Harri Kiiskinen, is attached to the Hankasalmi Observatory radio telescope. In the past, only one other automated eye for halos has been in use. It was operated by Nicolas Lefaudeux in Paris for three years, and showed that odd radius halos are in fact common. Now let's await for the discoveries from Hankasalmi.

21.10. On Tuesday at 01:50 Petri Kuossari photographed an occultation by asteroid 980 Anacostia in Tervakoski, Janakkala. The about 70 kilometers wide asteroid was 1.308 AU from us at the time of the event and passed on front of a 10,5 magnitude star. The video Kuossari made shows the occultation beautifully combined with a light curve. Kuossari sent the observation to SETI Institute and expects more detailed data on the occultation in a month's time

20.10. Last night a wide warm front with its rains approached Finland from west and the high cloud sheet which advanced it showed halos all the way from Lappeenranta to Salla. Here is a stack of the display taken by Petri Martikainen in Juva at 21.06-21.16. In the upper left corner of the picture is short-lived 120° parhelion, which Martikainen also noticed visually. If the 120° parhelion has been cut off from the news image, see Martikainen's observation .

20.10. Erik Pirtala got ready the less frequently photographed object Abell 85, which is a supernova remnant in the constellation of Cassiopeia. "The project, which started right in the very first days of the month, came to an end last night when even Eastern Finland got a glimpse of clears skies," says Pirtala. The total exposure was 17 hours. Abell 85, also known as CTB1, is located 9,800 light-years away from us and its size in the sky is that of a full moon.

18.10. Nasa launced on Saturday, Oct. 16, Lucy mission on its long journey to explore Jupiter Trojan asteroids. Arto Oksanen captured the probe next day with the Hankasalmi Observatory's 40 cm telescope. Lucy was 600,000 km from us at the time of the photo. The spacecraft will initially remain close to Earth's orbit and will pick up momentum from three near-Earth bypasses during its flight.

15.10. A piece of reflection rainbow rises from the base of the primary rainbow in this picture, that Tuula Sillanpää took at Tornio River on 13 October. This year, the reflection rainbows have been scarce. The first sighting in Skywarden came no earlier than the end of August, and Sillanpää's observation now is only the third. However, there is still time, the latest case in Warden's statistics is from November, and nothing in principle prevents sightings in December in areas where there is open water.

14.10. The drab October cloud cover eased its grip on the night of 12/13, when suitably also northern lights were visible. One of those out with camera was Jari Ylinampa, who got lucky with a fireball shooting across the video he took in Rovaniemi. Here are three screenshots, but it is worth checking the actual footage from Ylinampa’s observation.

10.10. Inspired by the Ursa Bongaa 100 challenge, Pekka Rautajoki drew the Milky Way. This was the challenge number 54, a really dark starry sky. "It is always nice to scan with binoculars the abundance of stars and the star clusters at the plane of our home galaxy, but it is still most impressive to look at the cosmos opening over the dark countryside with the naked eye", tells Rautajoki.

5.10. Reflections of outdoor lights in ice clouds high up created last night a map of Pieksämäki in the sky. The phenomenon was photographed with a compact camera by Timo Kantola after he first noticed it from his fireball camera images. “With the naked eye these were barely noticeable,” Kantalo says. From the sky map one can distinguish, for example, the city main street, railway area and the yellow lights illuminated national road 23.

4.10. The rather sparsely photographed Flying Dragon nebula was immortalized in gold tones by Erik Pirtala. Also known as Sh2-114, this target lies at edge of the Cygnus constellation. Exceptionally, only two narrowband filters, H-alpha and S-II, were used instead of the normal three. “I didn’t photograph the O-III channel this time because it’s really, really dim here,” says Pirtala, who adds that the post-processing was difficult due to the lack of balancing blue color.

4.10. The Wizard Nebula or NGC 7380 in the constellation of Cepheus is a good target this time of year as it rises high in the sky. Antti-Jussi Pyykkönen started photographing Wizard Nebula last autumn, but the project was interrupted. Now, a year later, he got the remaining exposures done and the result is seen here.

3.10 . The comet 29P/Schwassmann-Wachmann is currently in outburst and is much brighter than normally, writes Bob King in Sky and Telescope. Here is a picture of the comet Timo Kantola took in Pieksämäki on 3.10. at 3.30. "Definitely a comet to follow if the weather allows," says Kantola. Known for its intermittent eruptions, Schwassmann-Wachmann orbits a little further than Jupiter on a relatively circular orbit.

30.9. Seven sightings of the northern lights on Tuesday-Wednesday night have been published in Skywarden. Green color dominated strongly in this show, the photo taken by Kari Rytilahti in Salla at 00.30 provides an example. These observations were made in locations north of Valtimo, none have arrived from the southern part of the country.

29.9. After having acquired a full set of narrowband filters this September, Antti Taskinen took IC 1396 emission nebula in the constellation of Cepheus as the target of his first color narrowband image. "This narrowband shooting with all its steps is a nice pastime, and it takes quite commendably time too," says Taskinen. The shape rising from the bottom is the Elephant's Trunk Nebula. Taskinen collected light from the object for 15 hours.

29.9. Ari Haavisto tried his new telescope for the first time on the Moon on September 27th. The result was satisfyingly sharp despite the weather not being the most favourable. In the middle, bottom-up, are craters Ptolemaeus, Alphonsus and Arzachel. The largest, Ptolemaeus, is 154 kilometers in diameter.

27.9. at 22-24 a light phenomenon caused by a rocket launch was seen in the Finnish sky. The incident is possibly related to what happened in California shortly after 9 p.m. For launching an Atlas 5 rocket. The rocket will take the Earth Earth Landsat 9 satellite into orbit. Apparently the same rocket phase with fuel clouds appeared in the sky twice. First at 22-23 after the launch and the second time after midnight after orbiting the earth once.

An observation of the case can be submitted using the Rare Clouds-form . Rocket launch is selected as the target. Photo by Mikko Juutilainen

27.9 . Markus Sinervä lifted his drone into the air this morning at Hausjärvi and was able to photograph the fogbow. Be sure also to watch from Sinervä's observation the video he made of the drone's flight. It shows in addition a small glory inside the fogbow. The experience is crowned by the ambient soundtrack of the drone's purring.

24.9. completed maintenance break brought new features to Taivaanvahti and opened the system in Swedish (Himlakollen) and in English (Skywarden) for users from Northern Europe. We hope that the changes will make the site easier to use for the Swedish-speaking minority and enable new forms of Nordic co-operation. The change would not have been possible without the support of the Svenska Kulturfonden and the effort that individual enthusiasts put into the translations. Warm thanks to everyone involved in the project!

23.9. Sh2-101, or Tulip Nebula, is a rarely described object, of which there are already five observations in Skywarden. Now Erik Pirtala has also taken the fog to the desktop and brought a strong sixth contribution , the color palette of which emphasizes golden tones. From the beginning of September, the object photographed received 15,5 hours of light.

23.9. The perimeter on a full moon was dramatically looking in Ikaalinen Sisätö the other night when it lit the Altocumulus clouds with an orange flare. The picture was taken by Heidi Rikala .

22.9. Artificial light pillars are familiar from winter ice mists, but they are also seen as short snippets in the crystal clouds above in other seasons as well. These Petri Hakanen 22.9. The pillars seen in Kokemäki in the evening are the first of the autumn season after Maija Perttola photographed the last of spring at midnight 13/14. April. The early observation after the summer break is from 2016, when Matti Helin spotted the pillars at midnight 24/25. July.

21.9. For the old people, the perimeter phenomenon could mean a change in the weather. However, this perimeter of the Moon last night was a sign for the pearl owl in the picture that a ring was coming to the foot. Petri Martikainen, who took the picture, ringed another pearl the same night.

21.9. In addition to high-atmosphere clouds, the Sky Watch special clouds category also includes six tropospheric clouds. Here are two of them recently described. On the left, the crests of the Kelvin-Helmholtz clouds seen by Georg Kieninger from a small cloud hole in Helsinki. On the right, Lasse Nurminen captured a horseshoe swirl that lasted just over a minute and was captured in Raisio.

20.9. The galaxy M33 in the constellation of the triangle is one of the basic objects in the night sky. This picture of Tomi Kurri is the second in Taivaanvahti after the summer break. M33 belongs to the so-called local group, the most famous member of which, in addition to our own galaxy, is the Andromeda galaxy. The exposure to Kurr's image accumulated a little on for five hours. Vesa Puistovaara took the first picture of the object in the autumn.

16.9. less than 30 observations have arrived at the Sky Watch from the fireball seen at 11:51 p.m. By far the majority of reports are from Turku and the surrounding area. According to Jaakko Visuri , the fireball working group, meteorites that may have survived from the atmosphere fell into the Baltic Sea.

15.9. Field, Milky Way and cyclist admiring it. It contains the ingredients for a composition that is worth stopping by. Kari Kangasluoma says that this is his first photo of the Milky Way this autumn. We look forward to the following variations on the theme.

14.9. During the days, photographs of the northern lights seen in the northern parts of the country on 10 / 11.9 nights have seeped into the sky. Seija Hakala took this picture on Pallas in Muonio when she returned from a rainy trip to Norway. "There was a belt, gauze and rays. I didn't know where to shoot," says Hakala. "The disappointment of the rain disappeared while watching the fire."

12.9. The swan constellation NGC 7000, or North American Nebula, is a vast target in the sky. While the full moon is half a degree in diameter, NGC 7000 covers an area of six degrees. The fog has fit well into this canvas made by Harri Kiiskinen , which has been parsed into one of the eight partial images. In the upper right corner shines the Swan star Deneb.

11.9. The launch of the Soyuz 2.1v rocket from Russia on 9 September was visible almost throughout Finland at 11 p.m. The lingering cloud-like clouds also remained in the upper parts of the atmosphere. We know of these Terhi Törmälä, who is returning from the Northern Lights, on September 10th. thanks to the images he captured at dusk. Attached is Törmälä's sample of the phenomenon at 4.50.

11.9. It is clear from the picture taken by Kari Kuure on September 10 that there is now enough comma in our daylight. Kuure says the sunspot number is 124, which is a big number at this time of the dot cycle. “Indeed, it appears that the activated Sun has evolved remarkably rapidly in a higher direction if compared to predictions,” he writes.

10.9. After yesterday at 11 pm, a rocket launch was seen over Finland and Sweden. The night was largely clear and this phenomenon, which lasted only minutes, has already become more than 50 observations across the country . Attached is a picture of the view taken by Pirjo Koski and Riku Poskiparra at 11.12 pm in Pyhäranta. “A dazzling silver-bluish light phenomenon that brightened in the eyes,” they describe the impression. Rocket launches are a rare treat in Finland, the previous one was seen in April 2019.

9.9. Inspired by the Finland 100 anniversary year, the project came to an end when the last of the 201 asteroids discovered by Finns was photographed on 3 September. The first observation of the project implemented by a small team in Artjärvi was made on March 24, 2017, when the target was the asteroid 1504 Lappeenranta. Attached is a shooting contract now completed for 7267 Victormeen. A small number of observers from other parts of Finland also participated in the project. Photo K. Laihia, V. Mäkelä, T. Veikkolainen, R. Päivinen, CO Cambiselis .

8.9. Two stunning interpretations have been uploaded to the Sky Guard from the neighboring galaxy Andromeda. Here is Aleksi Ruotsila's version , which is already the Fifth for him. “I didn’t spare with colors when the image data was good for once, and there was no need to fight with noise,” says Ruotsila. The exposure accumulated for a total of 10.3 hours. One of the pictures was taken by Erik Pirtala .

7.9. Satu Juvonen's landscape planet picture shows Jupiter and Saturn. The former is so bright that it has been surrounded by a mist rising from the pond. Juvonen says the image is a minute's exposure with tracking.

6.9. Eero Karvinen photographed the northern lights in the morning hours of Sun-Mon night. This image, dominated by green and blue shapes, has captured the sub-storm that occurred at 3 p.m. "The blue rays were distinguishable for a while," Karvinen writes. He also sheds light on the formation of color, which occurs from "a suitable mixture of cationic nitrogen molecule and atomic oxygen emission."

6.9. For the third time in a short time, a handsome halo show is seen in the north facing the country. This time starring halos that emerged from tile crystals. They created a horizon ring with a powerful 120 ° side sun and an arc of a bright zenith environment shining high into the sky in the spectrum. Here on the left are photos of Joni Alavesa from Simo and on the right a sample of I from an anonymous observer.

6.9. The drone offers the photographer a longer hand than a natural light photographer, especially when it comes to fog phenomena. Petri Martikainen had been waiting for foggy weather for a long time to get his drone into action and finally succeeded this morning. A mist mattress less than 50 meters thick was beautifully drawn by a thick fog arc and a small gloor disc. A few days earlier, Vesa Toropainen photographed a similar view while soaring down above the clouds.

5.9. Antti Taskinen is annoyed when Jupiter is in such a low sky at these latitudes. But "nonetheless, some frenzy drives the telescope toward this planet whenever possible," he writes. Several others have done the same. In order from right to left, the photos taken by Ari Haavisto and Tauno Ihalainen in the same month have been selected to accompany Taskinen's August Jupiter.

5.9. Harri Kiiskinen's findings provided a comet review. On the left is the brightest comet of the moment C / 2019 L3 (ATLAS). It could rise to just over 10 mag early next year. Next to C / 2017 K2 (PANSTARRS), which is expected to be at its brightest at the turn of 2022/23. Next is C / 2021 A1 (Leonard), which by Christmas could become a 4-5 mag comet. And last on the right is C / 2020 PV6 (PANSTARRS), whose 14 mag brightness barely rises.

4.9. Petri Martikainen photographed the main and side raincoat combo in the bright flashlight spotlight. The picture illustrates well how the main rainbow is actually a light disk with the strongest outer edge showing the actual arc. The dark Alexander zone between the main and side rainbow, which receives little light, also emerges as strong.

3.9. The night cloud observations ended on 23 / 24.8. to the night and no clouds have been seen in the satellite images either 27.8. so the season can be considered over. The summer provided as many as 51 nights of night clouds, which shares the gold rank of statistics starting in 1995 with 2018. The number of nocturnal nights in June, July, and August was 12, 24, and 15. No clouds were seen in May. The picture shows the night clouds seen by Satu Juvonen 10 / 11.8. In Kontiolahti .

3.9. Ari Jokinen picked up a section called "Cygnus wall" from the North American fog as the driving force for the DeepSky season. At this point in the nebula, corresponding to Mexico and Central America, star formation is strongest. A total of 18 hours of material accumulated from Jokinen's exposures on the nights of August and early September.

3.9. When the north röyhisteltiin yesterday logs impressively , had to settle for the south 22 ° ring perusrinkuloihin. But Petri Martikainen's 6-minute series in Juva included a particularly noteworthy companion for the 22 ° ring: the 28 ° ring. This halo, the crystal of which has not been seen, has been photographed in the sky only fifty times. The picture of the phenomenon that Martikainen now receives is in a class of its own in its clarity.

3.9. Kari Kuure went through the recordings of the Tampere Ursa weather camera from the maximum night of the sun rows from 10.30 pm to 4.30 pm and found 18 flocks of meteors. Here are half of them. According to the latest, constantly updated information from the IMO, the peak of aurigids was 00.40 Finnish time. On both sides of this was an hour of unusual activity. ZHR had a maximum of 90 surfaces. The number of star flights seen was reduced by a low radiant in Europe, writes IMO's Robert Lunsford .

3.9. Erik Pirtala's workshop becomes this masterpiece of deep sky. “Getting the opening image of the season ready is always but such an inexplicably awesome feeling,” he says. This is a subset of the object known as Harsosumuna, NGC 6992. This time, Pirtala decided to invest in the gold-colored Hubble palette in his filter choices, where this Swan constellation object is less often seen. The exposure accumulated for 17.4 hours.

2.9. This year, Northern Finland will see the brightest halo performances of the upper clouds. First enjoyed on August 3rd and now on Thursday 2.9th. appeared again. Here are Vesa Särkelä's views from Kemijärvi . Of course, rarities are also expected to fall from the halo complex of this level, and the best forms in Jani Päiväniemi 's observation at Ruka were Wegener's counter-solar arc and counter-sun.

2.9. Pekka Parviainen worked the four-year-old asses into a meteor storm in one picture. “I imagined the contract to be a 2-3 day rush, but it took an estimated 100 hours to see it,” he writes. Meteors from 2013, 2016, 2018 and 2021 are included. The wallpaper is from 2016, when Parviainen stayed to shoot in the city. Parviainen also published five other pictures in Taivaanvahti in which he collected asses.

2.9. With the darkening nights, the telescopes have once again been aimed at the depths of space and the opening catalog of the season has been brought to Vahti. Here is Tomi Kurr's testing of the new Celestron RASA 8 F / 2 tube last weekend under the sky of Nakkila. The target is the familiar Andromeda galaxy M31 as well as its satellite galaxies M32 and M110.

1.9. The predictions hit a button when the maximum of the Aurigide meteor flock was observed last night at 00.35. In this case, ZHR, which is calculated from the number of shooting star ihmishavaitsijalle hours in optimum conditions, the IMO, by momentarily 60-100 (figures may sharpen). These twists and turns also hit the pinnacle of radio observations. In Finland, Markku Ruonala saw 6 aurigids in a 55-minute observation period. Attached is the aurigidi photographed by Petri Martikainen.

1.9. Pia Simonen was in Asikkala's Pulkkilanharju yesterday alert to the fog immediately at sunrise, but the phenomenon refused to show up. When Simonen then fell asleep and woke up again, the fog was handsome in the sky . "Luckily I was in a hurry, the arc disappeared within minutes of taking the pictures," says Simonen. The weaker sections of the arc on the water surface are not reflections of the fog arc, these images are formed in different droplets.

1.9. The cloud photographed by Tapio Kivihuhta in Vöyri yesterday looks like it has traces of an animal's paw. A phenomenon called a hole cloud is a partial transformation of a cloud of subcooled water droplets into ice crystals. Some observations are made from the hole clouds to the Sky Watch every year.

30.8. Markku Ruonala says that he noticed a few aurigids during the Sun-Mon night. An exceptional eruption is forecast for the flock at the turn of the month at Ti-Wed night. Near midnight in about half an hour you can see roughly 20 star flights. Veteran enthusiasts, of course, know that surprises can come beyond the prediction. The aurigidi in the image of Ruonala is a dimmer streak at the top, with a light bank left by an airplane in the middle.

30.8. Our day star currently has an impressive comma group of 2860. The comma area has spread over an area of 200,000 kilometers on the surface of the Sun. The attached photo of Harri Kiiskinen was taken yesterday 29.8. at 10 . The Hankasalmi Observatory radio telescope has also observed flare eruptions caused by a comma group, of which the strongest 28.8. at 9.23 reached the second highest M-class.

29.8. Eemil Pietilä photographed our wanderer in Järvenpää this morning at 2 o'clock. The 80 mm Orion ST80-A lens telescope had a 2x Barlow and a dimmable moon filter. After stacking, the result could be satisfied. "The most accurate moon I ever took," says Pietilä.

28.8. Northern lights have been observed since 6 / 7.8 nights, last night 27 / 28.8. already got a slightly better show. As an example, this picture of Pertti Rautiainen from Oulu at 00.30. "Quite bright northern lights were visible in the whole sky, in addition to them a little brighter bands from time to time," writes Rautiainen. According to the Finnish Meteorological Institute's forecast, the next better chance for northern lights seems to be Sun-Mon night.

25.8. There has been time to wait for the reflection rainbow. In the previous year, they were seen on 12 different days and on the previous five days. If only this reflection rainbow captured by Jussi Laamanen in Poland four days ago would be just the opening of the game this year. The latest reflective rainbow in Vahti, observed in Finland, is dated 19.11. in 2016. Last year, the season ended on 13.10. until.

24.8. On Tuesday morning, night clouds were photographed both in Iisalmi - with the attached photo of Riitta Kumpulainen - and in Kurika. This is the latest finding in the (partly incomplete) 1995-2021 material available online. Later ones may be found in unpublished years. According to a study by Jarkko Alatalo , the last possible night cloud night in southern Finland would seem to be 19 / 20.8. In the north you can see the clouds later.

23.8. Eemil Pietilä's shot of the setting sun from Soavu's Kasavuori in Espoo exudes serene simplicity. It was a test of a new solar filter last Friday for an 80 mm Orion ST-80 lens telescope. "The setting sun captured the camera in a nice color," says Pietilä.

18.8. Observations have been made in the skies in northern Finland 3.8. of the higher quality halo play seen. The rarities found in the pictures are e.g. Lowitz Arches, Wegener's Counter-Solar Arc, and Solar Arc. The last of these is a particularly good bonga in the upper clouds. Here is Kalle Helenius' picture of the show on the Muotkatunturi hiking trip. “Both towed camera systems immediately got to a good job,” writes Helenius.

15.8. A handful of photographers were on the move after the storms on the night between Friday and Saturday. This picture was taken by Lajo in Pirjo Koski at 11.18 pm. Juha Ojanperä and Riku Poskiparta were also present. “Thunder cells traveled both west and east, but none came all the way or even very close,” they write.

15.8. The cameras of Harri Kiiskinen and Timo Kantola (pictured) recorded a lot of asses also on the night after 13-14.8 after the maximum. In fact, on the IMO website, Robert Lunsford says that in the morning of that night in the United States (when daylight hours in Finland), observers had seen 2-3 times more assists than what was seen at the actual maximum. The analysis of this unexpected outburst is still ongoing.

14.8. The maximum of Perseids has become pictures from more than 20 enthusiasts from all over Finland. In two hours, Jari Luomanen recovered 26 star flights estimated to be asses, of which he composed 18 pieces for the sum picture shown here. "There were even bright hits, even though the best of course flew outside the field of photography," says Luomanen. The stronger flashes on the right and left sides are the satellite and the sporadic starburst.

12.8. Lasse Nurminen annoys the gauze clouds of his yesterday's picture, but it is not out of the beautiful colors of this sample. At the same time, the image also reminds us that there is no harm in the Moon at the time of the imminent Assassin peak. With the maximum peak hitting almost in the middle of our short night this year, the starting points are as good as possible.

12.8. When there are no natural light sources for optical phenomena, you can use your own. In the evening, Lasse Nurminen tried to get a fog in the light of the sun. This was not possible due to the delicacy of the fog, but it was thicker at night and Nurminen decided to peek at the views in the car lights. There was a great fog arc display with interference arcs and even a small amount of chlorine can be seen.

12.8. Next night 12-13.8. asses occur the most. The maximum of the three-hour peak this year is forecast to hit the night time at 22-01. In the south of Oulu, where the nights are dark enough, there would seem to be a wide range of clear skies as well. The picture shows the asses of Harri Kiiskinen's Nyrölä fireball camera from last night . In four hours, 40 asses grabbed the camera.

11.8. The night cloud season is already in the evening, but again we got a beautiful view last night. The model is provided by a picture taken by Jari Luomanen in Tampere, in which a more limited area from the show has been selected with a telephoto lens. "A nice bright play with very sharp shapes," writes Luomanen.

11.8. The thunderstorms of the last few days have become a few observations for the Sky Watcher. Here is the footage of Juha Ojanperä 's yesterday's bonga trip from Nakkila. Ojanperä waited for the situation to develop in the field opening of Lake Leistilänjärvi and got a lightning strike close to the video when the air was at its harshest. "At this point, I was in the middle of a downpour that was accompanied by heavy rain, wind and also hail," Ojanperä writes.

8.8. The grips just get better as the ass maximum approaches. For four nights in a row ( Harri Kiiskinen), the Nyrölä meteor camera has recorded increasing numbers of starbursts. The image below shows the persides of the night between last Friday and Saturday. This 17 ass booty comes from Timo Kantola's Pieksämäki camera. The maximum of Perseids is on the night between Thursday and Friday.

7.8. Harry Rabb has realized a long-term project by filming the movement of the Barnard star in the sky over four years. After the three-star Alfa Centaur, it is the fourth closest star to us at six light-years away. The angular motion of an object in the sky is the largest of all the stars. In 90 years, the Star of Barnard wanders about a quarter, or half the diameter of the Moon.

4.8. The dark skies of August and the low night clouds below are a sight worth watching. This is the latest model from the night between Tuesday and Wednesday, the picture was taken by Markku Ruonala in Urjala . The steak was a clear redness at the top of the clouds and asshole was also included. On the same night, 8 asses and two kappa cygnids had caught Harri Kiiskinen's meteor camera.

3.8. The maximum of Perseids is still a week, but the first star flight of the flock has already been filmed. The perpetuation of this Perseid car 1.8. at 2.02 Harri Kiiskinen's meteor camera. The maximum of the Star Flight Flock hits 12-13. August night. As far as it is clear, the conditions will be good this year, as there is no harm in the Moon.

1.8. Matti Helin spent the turn of the month driving after the thunderstorms, when a violent air zone arrived in southwestern Finland that swept across the country. “Decent lightning bombing only started in four countries in Lieto,” he writes. Here's a model of the lightning strike at 4.35. Jouni Hovi also managed to get a few flash pictures in Piikkiö and Jorma Mäntylä during the day in Sahalahti.

1.8. A handsome avalanche surprised on Friday, July 30th. Jari Ylioja at Nivala. Elsewhere in the country, no avalanches were observed on the same day. The most avalanche cloud day of the summer was 23.6, when 27 photographers put their shots in Vahti from all over Finland.

31.7. Mikko Peussa weighed the situation yesterday and decided that if he drives 25 km from Turku to Paimio, there could be a rainbow of sunset. “It seemed like I could make it to the scene without speeding,” he says. And everything hit as it was: there were no clouds in front of the Sun and it rained properly on the opposite side. "Little by little it became one of the most beautiful rainbows I've photographed."

29.7. It seems like there were only two negative night cloud observations last night. Thus ended the Sky Watch and probably also the longest night cloud tube ever in Finland. The night clouds were seen for 19 consecutive nights, starting on 9 / 10.7. This far surpassed Vahti's next longest uninterrupted series of statistics starting in 2011, 12 nights in 2015 and 2020. Here is Arto Oksanen's picture from the last night of the record period 27 / 28.7.

28.7. Yesterday we received pictures of udder clouds from the south and north. On the left, Anne Sarajärvi's rap on the post-thunder evening sun mothers in Sodankylä. On the right is Mikko Peussa's picture of a more special case that did not involve thunder. “In the evening, a handsome cloud front flooded from the sea,” Peussa says. "Occupations formed and disappeared several times to the edge and below." Paula Mattila also recorded this formation in the Turku region.

27.7. The planets are beginning to become an even higher quality image. Here is a good shot of Tomi Kurri from Jupiter in Nakkila on July 25 at 3.50. “When used, the busy Meade got into the first true test, a surprisingly good planetary tube,” Kurri writes. The picture also shows the three moons of the gas giant, Europa, Ganymede and Io.

26.7. The nights will inevitably get dark and warm-up for the upcoming DS season has already begun. In the middle of Jukka Laakson 25.7. the exposure is Lyra's tire fog M57 . On the left, in turn, is the large spherical constellation of Hercules M13, illuminated by Santeri Peltola for four nights. And on the right is the "extreme astronomy" of Tapio Lahtinen's very bright sky. The target is the Lifting Weight M27 , which Lahtinen photographed in Tampere as early as 28.6.

25.7. Jupiter and Saturn have been in the sights of enthusiasts since the beginning of July. On the left, a fresh picture of the ring planet by Tauno Ihalainen last night. On the right, Tomi Kurr's sample of Jupiter 18.7. Both planets are low, so the turmoil of the atmosphere makes it difficult to describe them. Venus has also been photographed from the daytime sky.

24.7. Let's take two pictures from the current lunar cycle. On the right, Jorma Koski's mood shot 22.7. In Porvoo. On the left Georg Kieninger in Helsinki 16.7 . Finnair's aircraft + Moon combo received as a result of rapid response. "But - it flew towards the moon," Kieninger writes. "Suddenly a long - tube camera on and off, focus on the subject, a few seconds of tracking and - click".

21.7. The night clouds are now at their best, the previous night’s outlook was the absolute peak of the season. Enthusiasts were awake in large numbers, pictures have already been published by 50 people. Here is a sample of Markku Ruonala's nights in Aka . “I’ve been watching the night clouds for over 30 years and this one definitely goes on the top 5 list of plays I’ve seen,” Ruonala writes.

19.7. As the night sky gets dark, more drama comes into the night clouds. Last night, observers agree that now was the best show of the season to date. "After all, it was a really good night cloud play this summer," commented Mikko Peussa on the prospects in Turku . Fifteen observers have so far put their pictures in the Sky Watch. Attached is a 40-minute animation by Peussa.

19.7. Yesterday's harvest of the Riikka violent air is this picture of Rauni Pakkala of the main rainbow shining brilliantly on the exceptionally low horizon. Since the radius of the red outer edge of the main rainbow is 42 degrees from the antipodal point of the Sun and the sun was at 38 degrees, the peak of the main rainbow has been four degrees above the horizon. A few days earlier, Kari Rytilahti filmed a great rainbow show in Hänvihaara, Mäntsälä.

18.7. Characteristic of the heather, halo rarities in July have been almost exclusively pyramid crystal halos. An example is shown in the pictures on the left 15.7. halo play. The upper stack taken by Petri Martikainen has all six pyramid rings and a 22 ° ring. The lower stack of Tero Sipinen shows the largest of the pyramid rings, the 35 ° ring. On the right, Reima Eresmaa's picture shows the reflection field sun in Joensuu on July 9.

17.7. In Kauniainen, Ben Kalland photographed the comma group of our star of the day with the Lunt 80mm solar telescope. The hydrogen alpha double filter used in the description nicely brought out the details of the Sun’s surface. "For once, the old curse didn't work - namely, as soon as I got the equipment piled up the heat started and EVERY EVERY morning has been clear," writes Kalland

16.7. The Sky Watch has received several observations of two cars seen in Thursday in southern Finland. The first of these appeared at 1.20 and it also grabbed Tampere's Ursa fireball camera , as can be seen from the animation above. "Earthgrazer-looking, just over 6 seconds of calm flight," says Markku Lintinen , who published the photos. Another fireball appeared around 11:50 p.m.

12.7. In July, two higher-quality night cloud displays have already been shown. The first was available on the night between the 4th and 5th day, here on the left is a picture of Pirjo Koski from Uusikaupunki . These were night clouds all over the sky, as can be clearly seen from the video that Tero Sipinen shot with a fisheye in Kouvola. The second show was last night, to the right of which was the recording of Pentti Arpalahti in Helsinki . These night clouds covered about half the sky.

11.7. A few great shots have already been taken of the rain walls this year. Here is the latest offer with lightning in Taivassalo during the second hours of the second night. "Rarely has a small thunderstorm cell provided such a great performance," says Eero Karvinen , who took the picture. The phenomenon can also be seen in Paula Mattila's picture of Kustavi . Previous spectacular rain walls are represented by the cases seen by Matias Takala in Kuopio and Jari Ylioja in Haapavesi in June.

30.6. Since June 18, night cloud observations have come in a relatively steady stream night after night. However, as in the early part of the year, they have been modest. Last night there was already better stuff on offer that gives a foretaste of the even higher quality shows in July and early August. Observations of these nightmares have so far been obtained from seven camera users. Here are Janne Sievinen's views in Espoo after 1 p.m.

24.6. Yesterday’s thunderstorm zone spawned a record number of avalanche cloud sightings on the Sky Watch in one day. The pictures have currently been displayed by a total of 18 observers, mainly from southern Finland. Here is Pauli Jokinen's model of an avalanche cloud in Helsinki . "Maybe a 15-20 m / s gust hit and raised a nice high sand cloud on the beach," writes Jokinen.

23.6. The thunderstorms of the last few days have been a good time to bong the storm phenomena. Juho Nousiainen waited in Muurame for the arrival of a thunderstorm front last night and got the lightning struck to start trying to see if the shock could catch a 240 fps video. After waiting five minutes, this worked and the slow motion video shows just how the ground lightning is progressing. Watch a video of Nousiainen's observation .

21.6. The latest issue 2/2021 of the Zeniitti online magazine compiles the findings of the Haloh April project. The magazine also contains the first part of the Mars 2020–2021 observation summary. Photo: Joni Alavesa .

18.6. There were fine mammoth clouds on offer in the Iisalmi region on Tuesday night, when the Vieno storm began to recede. The clouds were recovered in Iisalmi by Riitta Kumpulainen , whose picture is attached, and a little further north in Vieremä by Hannu Laukkanen .

10.6. Today, there was an excellent setting for observing the partial solar eclipse, as sunny weather was available almost throughout Finland. So far, Taivaanvahti has received half a hundred observations from the southernmost part of Finland to Ivalo . Attached is Petrus Kurpa's view of the darkened Sun in Turku .

9.6. Enthusiasts recorded the thunderstorms that occurred in Western Finland yesterday afternoon. Attached is a photo of lightning taken by Eero Karvinen with a trigger in Tammela at 15.55. "The lightning spectacle hit the spot for a long time," Karvinen writes. "In about a quarter, the camera took more than 200 pictures until the battery ran out."

7.6. The edge of the sun shows a variety of movements in Timo Kantola 's animation for 26 minutes. "On the left, the dimmer protuts - maybe at an altitude of 20,000 km remain quite in place, from the bottom the magnetic fields tear the rags towards the surface of the sun," Timo Kantola describes. "In the middle, a large 'tornado' revolves around itself and plasma is thrown from the outer perimeter in every direction. On the right, two fine arcs appear and disappear immediately."

6.6. In Juva on June 3, a halo play stacked by Petri Martikainen found a 13 ° ring in addition to the usual pyramid halves. Signs of this rarity in the hard class have been seen in Finland in only one previous halo play, the case now described by Martikainen is the first clear observation. The ghostly 13 ° ring is a challenging target for the halobongo, because getting it properly always requires practically stacking.

5.6. Several observers took pictures of the first night clouds of the summer seen last night. For statistics that go back 10 years, the start time is typical. In most years, the night cloud season has started right between the end of May and the first third of June. The best screenings will be available from mid-July. Here is Pentti Arpalahti's picture of last night's night clouds in Helsinki at 1 o'clock.

3.6. The season for pine pollen starts cautiously as early as May 23, but only now is it beginning to gain momentum. Here are two pictures of a pine pollen yesterday in Naantali taken by Lasse Nurminen. "There is a lot of pollen on offer, and a lot of particles accumulated on the equipment during that shooting," writes Nurminen.

1.6. Mars was closest to Earth in October last year and enthusiasts took a lot of pictures of it. Lasse Ekblom has now compiled his shots from last season. The result is a projection of the entire surface of our neighboring planet, as well as this spectacular animation of the rotation of Mars.

29.5. The spots have been visible in the Sun throughout the spring. Here is a picture taken by Petrus Kurpa in Turku yesterday. Right on the edge of the Sun is the comma group AR 2826, inside AR 2824.

20.5. Late on Wednesday evening and night, a heavy thunder swept over Central Finland. According to the Finnish Meteorological Institute, 8,000 ground lightnings were registered per day, which is normally the balance for the whole of May. Attached is Harri Kiiskinen's picture of lightning in Jyväskylä , where the loudest brawls were experienced. "I don't remember the last time such a handsome show would have hit home corners. It took three hours from the screen," Kiiskinen writes.

17.5. Bea Degerth found in Turku on 13.5. from the video he took a light phenomenon that looks like a fireball . Five frames from the video have been captured in the animation below. The phenomenon seen in the twilight sky moves to the left of the image. In good weather, there might also be a video from the car camera about this. If such are found, they will be happy to be received on the Sky Guard's firework form . The phenomenon was seen at 10:22 p.m.

17.5. Jyri Nousiainen photographed fine spectral colors on the surface of a salt pond in Pälkäne on 14 May. This is a phenomenon caused by the alga Chromophyton rosanoffii. This unicellular gold alga rises on the surface of the water on the foot it builds. The light phenomenon comes from countless round algal cells on the surface side by side, five micrometers in diameter.

15.5. The thunderstorm of summer 2021 has opened spectacularly compared to many previous May. Saturday 15.5. In southern Ostrobothnia, spectacular avalanche clouds were observed during thunderstorms. The attached observation of Esa Palm was made in Kauhajoki.

10.5. Tommi Rimpilä posted a video of a horrible whirlwind seen on May 8 in Kannonkoski. "In calm weather, clicking on the fingers started to wind and this ended in just as clever," says Rimpilä. According to Rimpilä, at the very beginning the vortex had been only 40 cm wide and 20-25 m high, but he did not have time to get a video of this.

10.5. Birch pollen rings are back in the sky after a two-year hiatus. On May 8 and 9, they were seen in southern Finland. Within a few days, the warming weather and sunshine provide excellent conditions for new observations. Here is Mikko Peussa's picture of a birch pollen ring the day before yesterday in Turku.

5.5. Jarkko Järvinen put his first picture of the deep sky for viewing. There are three items available. The red fog that dominates the view is Sh2-129, known worldwide as the Flying Bat Nebula. In the middle of this rests the blue Outters 4, or Squid Nebula. The third target is a small fog at the bottom left of the image, VdB-140. The shooting, which took place mainly on the nights of April, accumulated a total of 22 hours of exposure.

3.5. The best cloud cloud play of the year so far is currently becoming reports from all over Southern and Central Finland . Among other things, the play has been found to look like a bright 22-degree overhanging and full horizon ring. There have been rarities in some of the observations. These include the lower solar arc, the Wegener counter-solar arc, and pyramidal halves at 9 and 18 degrees from the Sun. (Photo by Pia Simonen)

2.5. It was in Helsinki on April 29. in the early morning visible bright reflection of the lower sun . The picture was taken by Krister Heikkinen in the Hermanninmäki district. The phenomenon has arisen in crystals falling down from a dark cloud in the background. Sunlight enters the crystals through reflection from water. In the picture, the halo is also bordered by reflected cloud rays.

2.5. Petri Kuossari described the passage of the exoplanet TOI 1811.01 on the night between March 19 and 20. The curve below shows the dimming caused by the event on the central star of the planet, including the results of two other observers. What is exciting, according to Kuossari, is that the overrun was delayed compared to the forecast. This may be a sign of other planets in the system.

1.5. After two dry years, it is now a record year for an ellipse. This Paula Mattila today on May Day in Turku Ruissalo seen ellipsihalo mark the tenth ellipsipäivää / night this year. The figure is lower than the previous 2016 record. How much will we be at the end of the year? According to the watchman's statistics, the trip may crash in mid-summer. Only in 2012 have ellipses been seen since July.

1.5. In April, the Sky Watch received observations of eight tail stars. Several dim comets were aimed at Artjärvi, C / 2010 U3 (Boattini) was only 18 in magnitude . The most popular comet in April was the C / 2020 R4 Atlas shown in the animation below. Its brightness is predicted to peak around 8 magnitudes just these days. The animation was filmed by Petri Kuossari the other night in Janakkala.

25.4. Paavo Korpela photographed the sky on the night of 25 / 26.9.2020 with the intention of capturing lightning from the upper atmosphere. The pictures remained on the card waiting, but now Korpela went through them, stating that he had succeeded in his goal . These fairy flashes appear as red beaches in the upper right corner of the image on the left. They do not appear in the comparison image on the right. In the comments, Panu Lahtinen estimated that the lower part of the fairies was at a height of 50 km.

24.4. The past period of clear skies made Pekka Parviainen watch the sunsets in Kustavi in case of weaving. "The horizon is clear every night all the way to Sweden," writes Parviainen. This image shows the outlook for the first evening of the six-day tube on 14.4. "A moderate flash of green hung on the horizon for a couple of seconds, but no great flash, intensified by the canvas, was created," says Parviainen.

21.4. As far as the weather allows, the best seams of the Lyrid meteor flock of stars will be seen next night 21 / 22.4. Here is a picture of the Nyrölä Observatory's fireball camera on the night of 18 / 19.4. meteors that appeared. Based on the analysis of the UA2 program, Harri Kiiskinen writes that three of these were lyric . A long period of clear weather is just coming to an end, the best chances for a cloudless sky seem to be in the metropolitan area.

17.4. Last night's good northern lights show got the photographers with their cameras out, on the left a picture of Satu Juvonen. The fireball seen during the fires also became well recorded. In addition to automatic cameras, it grabbed at least five basic cameras, Lasse Nurminen's picture on the right. Soon the lightening sky leaves the northern lights shooting for a summer break, but still has time. In 2014, the fire was filmed on the night of May 8 and 9 as far as Kuusamo.

14.4. "For a long time, I wanted to photograph the star trail in a way that shows nothing but stars and birches reaching for the sky," says Panu Pahkamaa . In the evening 19.3. this then came true when there was clear and completely calm weather. The exposure to the streak image was 2h 47m.

14.4. Last night, clustered images of the rare under-reflection sun were obtained from the Helsinki metropolitan area (above left to right, images of Risto Ennevaara , Veronica Laitinen and Petri Pänkäläinen ). The phenomenon arises when sunlight is reflected from water and ice crystals, but not all of its characteristics have been explained. In the same cloud, pillars of artificial light were visible after dark . In several observations, the light source of the phenomenon was Neste's Porvoo refinery.

13.4 . Erik Pirtala's picture shows a supernova remnant W63, "Cygnus Shell". Pirtala says he was originally doing a 20-hour project. “But when I realized how dim the oxygen backbone of the supernova residue in particular is, it became an order of magnitude bigger than what was done in the project,” he writes. The light from the explosion of the star that produced the supernova remnant arrived on Earth about 15,000 years ago. The remnant of the star itself has not been found.

11.4. Last night at 12:07 a three-second green fireball skewed in the sky. So far, 14 observations have been made, all from a relatively small area in southern Finland . Above is a picture of Panu Lahtinen's Espoo automatic camera from the car. Sami Multasuo , who happened to be filming the Milky Way in Espoo at the same time, says that the fireball was broken into more than five parts.

11.4. "Goodbye dark sky," writes Satu Juvonen . The days are getting longer and the nights are getting shorter, and the Milky Way is no longer visible. Juvonen took this spectacular picture the other night in Suomujärvi, Patvinsuo.

9.4. Yesterday, a fireball was seen on both sides of daylight. The car that flew in the twilight sky at 5.35 has received 17 observations from the Sky Guard, one of them from an automatic camera. Another fireball appeared at 10:28 p.m. It is currently represented by nine observations , three from these automatic cameras. Both cars lasted four seconds. Above, a rapture from the early night car at the Warkauden Cassiopeian Cloud Observatory.

The group's annual halo-April campaign for optical phenomena in the atmosphere has been launched again. The first days have offered mainly basic dishes, such as the attached Markku Ruonala 4.4. see a 22 ° ring. An exception to these is the ellipse halo play observed by Jani Päiväniemi 2.4. In Kuusamo. More about Halohuikuiku in the news of the Zeniitti online magazine .

5.4. The harvest of the spring season in deep space images is represented on the left by Abell 21 and on the right by IC 1396. The former was photographed by Erik Pirtala in collaboration with Canadian Tudor Chibacu . They were allowed to collect 22 hours of exposure from this planetary nebula of the constellation of Gemini. The latter object, Kefeus' " Elephant's Trunk Nebula ," is a production by Ville Miettinen . He says he photographed it for six nights in small clouds, for a total of 13 hours.

2.4. This year, 20 new comets have been found. Here is one of them in Harri Kiiskinen's sample, C / 2021 D1 (SWAN) . It was spotted from images from the SOHO sonar SWAN camera in February. The brightness of the comet currently migrating in the constellation of the triangle is already declining, Kiiskinen gives it a magnitude of 11.4. The comet is at its highest in the evening sky.

1.4. The season was opened by Timo Alanko on March 30. In Vaasa. Petri Martikainen in Juva and Markku Siljama on Mäntyharju, pictured above, came to Vanavesi the next day. There must be an alder whose bloom has begun in the southern parts of the country. The earliest observations of pollen rings in the Sky Watch are on March 23rd. On that day, the rings were seen in both 2017 and 2019.

31.3. As spring progresses, the Sun has increasingly been the subject of observations. Here is a picture of protuberance taken by Santeri Peltola in Turku yesterday late in the afternoon. According to Peltola, there were at least three brains on offer. “I quickly had to choose a subject to start shooting because the sun was already setting,” he writes. Peltola's observation also includes a video showing living in protuberance.

25.3. The occurrence of pyramid halves filmed by Mikko Peussa the other night in Turku is a clear sign of the arrival of halo spring - in winter, such diverse pyramid shows are not available. The rarest form is the lower 9 ° best. It contains observations from the Sky Watch from 20 different days or nights since 2006.

24.3. Enthusiasts have photographed the nova N Cas 2021 glorified in the constellation of Cassiopeia, discovered by Japanese Yuji Nakamura on the 18th. Here is a picture of Harri Kiiskinen on the 21st. According to Arto Oksanen 's observation on the 22nd, the object had a magnitude of 7.7, the same as three days earlier. Oksanen also measured Nova's spectrum.

23.3. The forecasts for the northern lights were good for the evening of March 21st and were obtained from all over the country, although in the south the show was eventually subdued. Lapland was served with a nice short-lived corona. Here is a picture of Yrjö Benson from Ylläsjärvi . “The animation rose to the zenith where the stunning Korona show began at 10:22 p.m.,” says Benson.

22.3. This year marks the 100th anniversary of the Astronomical Society Ursa. The challenge of the anniversary year is to spot 100 phenomena. Many of the items on the list are also part of the watchdog's observation program. As a rule of thumb, the Sky Watch collects all photographic observations of space objects and most atmospheric light phenomena. If the Sky Watch detects the target of the Bongaa100 challenge, we hope you mark it as #bongaa100. (Photo by Eeva-Kaisa Ahlamo)

19.3. A few days ago, Pekka Parviainen posted a special satellite image to the Sky Watch five years ago: the wire drawn by the satellite has a red brightness. So far, it has been suggested that the satellite used its orbital engine as an explanation, but otherwise the commentary department has been silent. The picture also shows a standard satellite line on the right.

17.3. Thirty observations have been made of the fireball that appeared in southwestern Finland last night at about 8:10 p.m. One finding was reported from the Swedish side. Estimates of brightness range from a brighter full moon to a brighter one from Venus. The colors reported are orange and green, and there are also a few mentions of the firing of the fireball at the end of the flight. (The car recorded by the automatic camera in Varkaus at the same time was shown in a different direction).

15.3. Tero Sipinen took on the task of identifying the satellites that appeared in the sky last autumn's ass night. "The 'thirteen in a dozen' cases that drew a steady streak did not cause any major surprises, but all the flashed or flashing cases ended up in more detail," says Sipinen. The oldest of the 16 sites was LANDSAT 4, launched in 1982. The picture shows the Iridium 28 sent on a 1997 trip.

12.3. There have been plenty of deep space objects in the sky in recent days. Here is one of them, the fog described by Erik Pirtala in the constellation NGC 2264 Unicorn. The golden and blue hues of the subject come from the three narrowband filters used in the shooting, S-II, H-alpha, and O-III. "You are less likely to see pictures taken in the SHO palette. However, you had to try them," says Pirtala. There is also a starless version of the object in Pirtala's observation .

8.3. The panoramic image taken by Antti Taskinen in Ilomantsi has two overlapping arcs across the sky. On the right is the Milky Way. The dimmer left side is rarely described as a zodiacal band (zodiacal band). At its right end is a zodiac light. There is also brightness at the left end. This round glow is also rarely described as a backlight, gegenschein.

6.3. Samuli Vuorinen published an impressive interpretation of the emission mist IC 434, which forms the background for the dark horse head fog. "With clear weather, I photographed this subject in short clips from November to February," says Vuorinen. The exposure in the image is 12 hours. There is also a version of the mountain from which the stars have been removed.

4.3. Enthusiasts have described the encounter of Mars and the Pleiades in the sky. On the right is Voitto Pitkänen 's view of the subject in Kuusamo. "I had to wonder which one would come first; reasonably dim or clouds? There would have been a draw and the wind was still rattling the camera," says Pitkänen. On the left is a picture taken by Pekka Parviainen with a star filter in Kustavi.

3.3. At the beginning of March, two high-quality northern lights were immediately available. Observations came from Lapland to Helsinki. Here is the northern lights 1.3. in the evening in Kajaani , photographed by Taisto Komulainen . "The northern lights of the moonlight shone surprisingly beautifully," says Komulainen.

27.2 . in the evening at 19.43 a spectacular fireball was seen in the eastern part of the country. In the western part of the country, a thick cloud curtain prevented the phenomenon from appearing. The fireball was also in the pictures of Petri Martikainen , who acted with the fastest reflexes. More observations on the case are welcome on the fireball form .

25.2. On three nights in mid-February, Ville Miettinen photographed the M78 , which was embroidered with dark and reflective mists. The fog is found in the constellation Orion. "The target is very low, so I didn't get the full benefit of the good quality optics of my lens telescope," says Miettinen. The exposure in the view is 9 hours. Another object published by Miettinen is the Emission and Reflection Nebula IC405 .

22.2. The current winter has been good for the misty arches and their cloud arc relatives. The fog arc seen by Sirpa Malinen on the Pallastunturi ski run is rare in that it has as many as three interference arcs inside the main arc. Abundant interference means uniformly sized droplets. Such a situation is observed in the fresh, newly born fog. As the fog ages, the dispersion of the droplets increases.

22.2 . Five days ago, Arja Savolainen saw red pillars on the sea horizon against thick clouds. "I was going to photograph the sunset, but the moderately thick cloud mass prevented the sunset from appearing properly. However, there were these special pillars of light on the horizon," Savolainen writes. The phenomenon that has given rise to the debate seems, on the basis of current knowledge, to be a rare reflection of the sun.

21.2. Ari Haavisto says that he has tested a new mosaic photography combination on the Moon. And the imprint is staggering - in the high-resolution versions of the Crescent Moon above, there is enough detail to look at. The computer grinds 600 gigabytes of video in 17 hours. "We are living in exciting times when the development of technology has made this possible," says Haavisto. Links to major releases are available in Haavisto's observation.

20.2 . Three spectacular galaxies in the same portrait - this view is known as the Lion Trio. The picture is the handwriting of Erik Pirtala , the instrument was a telescope from the Härkämäki remote observatory. "The project, which was not completed in the spring of 2020, finally came to an end when I was finally able to collect the 20 hours of exposure I wanted," says Pirtala. The galaxies are M65, M66 and NGC 3628.

19.2. The cool winter atmosphere exudes a canvas picture taken by Pekka Lähteenmäki in front of Helsinki. "I was walking on the shores of Lauttasaari and I saw the fabrics again," says Lähteenmäki. The clothed object is the Harmaja lighthouse. It is 6.5 kilometers from the southern tip of Lauttasaari.

19.2. In Kuusamo , Jani Päiväniemi photographed the street map of her home village in the yard in the sky. The pattern was created when high-altitude ice crystals reflected back the light from street lamps. "It was nice to see this phenomenon again," says Päiväniemi. In 2019, Päiväniemi will record an even clearer cross of street lights above Käylä.

19.2. The observations of the Sky Watcher can now also be browsed with a mobile phone application developed by Pekka Keränen ( Geosaaga Oy) . Unlike previous mobile apps, the new app will also work on devices running Apple’s iOS operating system , such as the iPhone. The browser app is also available for download to Android phones (including Samsung, Huawei and the latest Nokia) through the Google Play Store.

18.2. "The comets that can be seen in Finland at the moment are dim," Harri Kiiskinen summed up the situation at the beginning of February. Here moves across the image field C / 2021 A2 (NEOWISE) photographed by Kiiskinen two nights ago, which was discovered this year. The link below shows the comet observations made since the beginning of the year. There are images from a total of five different comets.

16.2. "Finally the forecasts looked a little better and we had to go to Lapland to describe the northern lights immediately," says Mikko Lönnberg on his trip to Muonio. And there was no need to return empty-handed. "Right from the first night, I was able to describe the wonderful fires in the middle of the cannons." Here are the moods from the slopes of Lommoltunturi on the night between the 15th and 16th.

15.2. “A little evening play at sunset,” writes Ben Kalland of his picture, with a saxophonist playing on a high hill 1.5 miles away. Kalland had calculated the height and direction of the sun in advance, but he did not know the exact altitude of the place and subject. This became a last-minute adjustment where the position of the model had to be moved ten meters. As a result, according to Kalland, the model came a little too close to the trees.

11.2. Timo Martola photographed the elliptical halo in Janakkala, which was born in the ice mist on the 9th. "In eleven countries in the morning, the fog cloud curtain in the sky had fallen almost completely; the crystals glistening in the air were really big," says Martola of the conditions. For one reason or another, elliptical halons have lived an exceptionally long life in silence. Martola's bonga is the first in Finland in more than two years. The previous one was seen in January 2019.

10.2. Spring winter is a good time to bonga zoo light. This year's first animal light was photographed by Pirjo Koski on 5 February. Lasse Nurminen , Antti Taskinen and Timo Alanko quickly followed. Here is a picture of Alango on February 8th. “Less often it is so clearly distinguished,” says Alanko. The zodiac light can also be seen in the fall. The only night in the dark for which there are no observations in the Sky Watch is December.

8.2. The day before yesterday, Mikko Peussa saw the reflected clouds of clouds in Turku and made a great animation of the pictures he took. "This afternoon, the conditions seemed to be possible, and the reflected clouds were spectacular," says Peussa. Reflected cloud rays are created by sunlight reflected from water. Clear ice is also likely to come into play in the winter.

7.2. The strange halo brightening observed in Denmark for the first time last summer is now also seen in Juva, Finland. "Clear brightness outside the 22 ° rinkula in the direction of 2 p.m. The finding confirms the interpretation that this is an independent halo phenomenon. The mechanism of brightness is unknown.

5.2. Lasse Nurminen writes that the surface of the rake has been in Raisio for more than a day. In such conditions, it is possible to spot a rare surface solar arc, and Nurminen managed to see the phenomenon yesterday. The fork of the surface solar arc may appear on the surface of the snow after a clear and windy weather. As of now, usually only one fork is visible, at most three have been noticeable.

4.2. After a break of almost two weeks, the observations of the northern lights have fallen on guard again since the beginning of February. Last night they were filmed extensively, from Utsjoki to the Turku region . An example of this photo by Markku Ruonala in Aka. "The expectations for the evening's appearance were not high, but only from there did a reasonably nice play develop," Ruonala says.

2.2. Yesterday , Georg Kieninger described the passage of the International Space Station in the Helsinki Seaport. “The clouds receded just like by order and even at just the right time,” Kieninger writes. The interruption in the track was due to the fact that the camera had to be rotated to get a full picture of the track. It is a panorama of two stacks with a total of 299 squares.Mar

3.2. Petri Martikainen lifted a drone into the air in Juva yesterday to photograph the ice fog caused by the snow cannon at the ski resort. "Hasamäki had the last day of the cannon and, fortunately, finally the sunshine," says Martikainen. In this view, the drone is at the top of the ice mist at an altitude of 120 meters. Against the ground you can see halos that are only visible below the horizon: the bright lower sun and the lower side suns.

31.1. "The only two cloudless evenings in January at the heights of Kuopio were really cold and descriptively really challenging. Here is the destination of the latter frost bridge, a dark fog around the constellation Taurus," says Teemu Holopainen . The exposure in the view is three hours. Erik Pirtala also took advantage of these clear nights and photographed the galaxies M81 and M82.

22.1. Two interesting halo observations from the last few days. On the left, the street lamp scenes photographed by Reima Eresmaa . There is an previously unseen arc between the side suns and the solar arc. Based on the sims, it could be the counter-solar arc of Wegener or Hastings. The surface halo play described by Petri Martikainen has a mysterious 28 ° ring. The snow surface offers a unique opportunity to describe the ice crystal that causes it.

17.1. The avalanche has been flooded with images of the cloud arc. Observations arrived from southern Finland to Siikajoki . There are also a few fog and rainbows. Here, this group of phenomena is represented by Matti Helin's view in Lieto today. Helin says, "It was a wonderful mist in the morning, and I decided to take a picture of the foggy, drizzle trees on the telecom.

12.1. Erik Pirtala published a picture of the constellation Kassiopeia from NGC 281, more commonly known as Pacman Nebula. "The stars became quite challenging, because when I photographed them last night it was 20 degrees below zero and, as a result, the main mirror of my tube was a little tight. The image has an exposure of 12.5 hours.

7.1. Ice mudslides were now seen in Turku, as the top two pictures show. They were taken by Mikko Peussa the other evening and yesterday at noon. The light column in the image on the left is a rare diffuse counter-solar arc, with the halos in the outside lights on the right. Below it, the view is a little further north, these side suns were photographed by Niina Laitinen in Varkaus. At the bottom right is Keijo Lehtimäki 's view of the side suns in Posio.

6.1. The season started late and sluggish. Mauri Korpi got the first pictures yesterday in Ilmajoki. "After sunset, light cloudy beaches began to appear in Rusko, which I suspected to be pearls. As the evening darkened, pearlescent came to the fore," Korpi writes. This morning, the same pearls were also photographed by Marko Myllyniemi in neighboring Kurika. Only once in the last ten years has the start of the pearl season stretched to January.

5.1. As a result of the freezing, ice mist was made a little further south. In Nilsiä and Äänekoski, a double-V was seen on the Sun yesterday. Here are shots of Nilsiä by Risto Honga (right) and Ira Rikkonen . There is also a great video from Rikkonen. The lower of the halos is an arc upstream of 22 °, the upper a rare upper convex arch of Parry. Both halos are particularly representative. In Äänekoski, the pair of arches photographed by Tiina Airaksinen was weaker.
