New features

An update was made to Sky Watch on December 28 , which brought new features to the system. Many users had hoped for the opportunity to quickly provide positive feedback on the finding. There are now two different like-type feedback buttons. The heart symbol can be used to indicate that you like the observation. The star symbol is reserved for observations valuable to the study.

90 observations from the Christmas comet

4.1. 90 observations of the tail star Wirtanen have arrived in the sky. The geometry of the comet relative to the Earth was such that the tail remained hidden or was at most very short. The days in the full moon region were awkward as expected. The best shots of the comet in Finland were taken before the moon became clearer. (Attached photo on December 12, Juha Parvio). After Christmas, the comet is already clearly dimmed.

A new halo form from Sweden was released in Taivaanvahti

14.12. Swedish star enthusiast Magnus Edbäck released a fierce halo play he filmed in Taivaanvahti in Borlänge today. Finnish halo expert Marko Riikonen identified a new halo shape in the image. The light spots on either side of the 22-degree overhanging arc are a new phenomenon of multiple scattering that has been known to make its world debut based on computer simulations.

The comet Wirtanen can be seen with binoculars

13.12. Cloudy weather has made it difficult to observe the 46P / Wirtanen in many places. However, the object can be found in the sky with binoculars at least for the rest of the month. The comet appears as a hazy ball even in a small amount of light pollution. At the end of the month, 46P / Wirtanen can be found in the area of the Taurus-Ajomies constellations. The search map can be found in Ursa's press release . Observations are collected using a solar system form (target: Comet, name: 46P / Wirtanen). Photo Victory Pitkänen

Ostrobothnia crossed earthgrazer on video

30.11. Markku Lintinen of the fireball working group released the video on 24 November. An earthgrazer-type fire that crossed Ostrobothnia. According to the analysis of the working group Janne E. Sievinen , the song traveled over Finland for more than 200 kilometers along the Maalahti-Pihtipudas line at an altitude of more than 90 km. The phenomenon was brighter to the naked eye. The event became visual observations from Viitasaari and Kuopio.

A wonderful ice mist play in Salo

27.11. Johanna Kuustonen photographed an exceptionally fine ice mist play between Salo and Perniö. The play featured several halorarities that were unusually sharp and bright on display, such as the arches of Moilanen and Tape.

Venus in the morning sky

18.11. In the morning sky in the southeast, a bright starry star is the planet Venus. Now that the observation weather has improved, you can explore the state of the starry sky on Ursa's star map page or by obtaining your own excursion star map. 17-19.11. over the weekend, several fireballs belonging to the Leonid star flight flock were also seen in the sky. You can also report to the Sky Watch your own fireball observation or send a pictorial observation of Venus . Photo by V. Pitkänen

The SAR arc again appeared in the Northern Lights play

4 / 5.11. on the night between the northern lights were visible on the northern horizon all the way to the south coast of the country. In the evening's northern lights show, the rarer northern lights, SAR arc, also stood out. The red and stable SAR arc appears dimly separated from the rest of the Northern Lights. You can record your own observations of the latter-day play with the Northern Lights form .

In this round, the comet will overtake the Earth at a distance of only 0.39 AU and its brightness is predicted to rise to the order of six magnitudes. Such objects can be observed with binoculars or a small telescope. Although the best observation time is only 10.9. around, a few observations have already been made. Photo by Harri Kiiskinen

11.8. partial eclipse

11.8. observations of a partial solar eclipse are collected using an eclipse form . So far, more than 50 observations have been received. Although the weather appears to have tentatively favored most of the country, those left under the cloud may record a negative observation on the same form. Photo by Satu Juvonen

Helle gave way with a handsome thunderstorm

1.-6.8. spectacular storm phenomena were experienced in many places. Especially 5.-6.8. the storms were also accompanied by several observations of funnel clouds, thrombi, and water columns. A funnel cloud reaching the ground is called a thrombus and a water column touching the water surface. Photo by Jari Ylioja

The lunar eclipse was widely seen in Finland

July 27-28 Complete lunar eclipse was widely observed, at least in southern and central Finland. Clouds and low fog, as well as the darkness of the Moon combined with a light sky, hampered the visibility of the early stages of eclipse. The partially complete phase, and in particular the partial phase of the rest, was monitored under better conditions. In some places in Ostrobothnia, the eclipse was completely clouded. (Photo by Marko Grönroos).

The moon darkens low between the southeast and southeast

27-28.7. on the night between, the weather allows to admire the complete lunar eclipse . The eclipse is best seen in southern Finland and is at its deepest at 11:22 p.m. Find an observation point where you can see the shallows between the southeast and the southeast. Report your findings to Sky Watch with the blackout form . Select Full Moon Eclipse as the title. If the phenomenon is covered in clouds, you can record an observation titled Eclipse Maximum Behind the Clouds. ( Photo by Marko Takala)

Great night cloud play July 25-26.

July 25-26 was seen as the best play of illuminating night clouds this summer. Especially near the southern coast of Finland, the lighting contrast was ideal. Even at the heights of Central Finland, the night clouds were clear. The Sky Guard map shows the distribution of observations with a clear latitude boundary . You can leave your own observation and photo with this form. (Photo by Markku Ruonala).

Get dark in Chile! Eclipse Journey 2019

Next July, the Sun will darken in the South Pacific and South America. The best place to spot an eclipse on solid ground is in Chile, where the eclipse ends just before the Sun goes down. The Stars and Space magazine and the Science Tube are organizing a trip to watch the eclipse. With the help of a local partner, we got 30 accommodations in the best possible region in Chile’s Elqui Valley.

Summer meeting in Säkylä 2.-5.8.

The birch pollen season began

7.5. Birch pollen rings appeared in the sky, perhaps a week later than normal. Abundant pollen levels in southern Finland created spectacular circles around the Sun. (Photo: Pia Simonen)

Opening of the thunderstorm

21.4. The storm season of 2018 started to the delight of the storm bongers on April 20-21. night, when there was a nightmare in southern Finland. Typically, the thunderstorm season begins in Finland in May, but it is not unusual in itself that there is already activity in April. (Photo by Matti Helin)

Haloh April began

1.4. the annual halo-april observation campaign was launched. The aim of the campaign is to observe as accurately as possible during April the halo phenomena visible around Kaarina around the Sun, Moon and artificial lights. Colors can also be seen in halos, but unlike rainbows, they are due to refractive phenomena in ice crystals. Report your findings on this form . (Photo by Marko Haapala)

31.3. the fireball ended up in the direction of Lavia

31.3. more than 140 observations have been received of the fireball seen at 9.08 p.m. According to Esko Lyytinen , the fireball working group, meteorites in the direction of Lavia may have survived from the piece. The object was very indistinguishable in the first images, which resulted in more throws than usual in the modeling. Finding one good picture fixed the situation. More photographic observations of the case are requested on the fireball form . (Photo by Aki Taavitsainen )

Minor remnants of a fireball in the direction of Hämeenlinna

27.3. Shortly after midnight, the bright fireball seen above Finland practically burned out. According to Esko Lyytinen (mathematician), a mathematician in the fireball team, small chips fell near Hämeenlinna. Several dozen observations of the phenomenon arrived in the Sky Watch. The fireball was visible over a wide area and there were a lot of pictures available for modeling from the meteor camera stations of the fireball team, only Northern Finland was covered in clouds.

Sunflower galaxy on a spring winter night

20.3. Spring winter and its galaxies are here, as Kirkariummi's comet Jari Saukkonen shows with his pictures of the Sunflower Galaxy. The finding includes a rare sample of the tidal tails of the same M63 galaxy in a false color image. The center of the image is connected to the center of the galaxy in the right color. A subtly confusing achievement with a telescope with only a 10-centimeter lens.

The bottom fire pipe continued for the fifth night

14.3.-19.3. One after another, the Northern Lights show has pampered celestial observers in recent nights. The attached animation by Jarmo Leskinen is from last night's views in Kempele. From this latest March 18-19. the play has now received a dozen observations by morning (see current situation ). The map view reveals the locations from which the phenomenon was successfully spotted. Submit your own report on the evolution form .

Great Northern Lights Play March 14-15. the night between

March 14-15 northern lights were visible along the southern coast of Finland. Mostly only the northernmost part of Lapland was covered with clouds. You can see successes in different locations from this up-to-date map link . Forty observations arrived. Notice the wonderful animation of vertical images from Jani Päiväniemi from Kuusamo and the animation of Vesa Vauhkonen's horizontal images from Rautalammi.

The morning balloon burned to the end in the direction of Pori

7.3. about twenty observations of the fireball seen at 4.37 in the morning have arrived in the Sky Guard. Juuso Nurmio got a great picture of the phenomenon in Taivassalo (picture). According to a preliminary assessment by Ursa's fireball team Esko Lyytinen , the piece flew in the direction of Pori. It had entered the atmosphere at a speed of about 30 kilometers per second. Such a high speed does not support a significant mass of entry, but the meteoroid has almost completely burned out in the atmosphere.

Rare elliptical fish for several days

22.2.-25.2. In recent days, meteorological conditions have been favorable for the formation of elliptical halos (see the top example from Mirko Lahtinen in January). Several enthusiasts have managed to photograph their first ellipse. The chain started with Jukka Kytömäki's observation on Mäntyharju, the northernmost report is from Laukaa by Janne Hakala , but the latest play focused on the Hyvinkää-Riihimäki-Orimattila axis. Picture from the play Pia Simonen .

Aldebaran was covered behind the moon

23.2. The star of the bull Aldebaran was hidden behind the Moon. The event was very noticeable in the evening from around 7.15pm to 8.20pm. The star cover is part of the ongoing Aldebaran cover series, the next events of which will be seen in Finland on March 22. and 19.4. More about star covers in the Zenith online magazine .

The little fireball went out over Kuru

24.2. at 00.04. A dozen observations of a small fireball that has flown over Finland after midnight have arrived in the sky. Esko Lyytinen of the fireball working group says that the target burned down almost completely. "Some little thing may have come down," Lyytinen estimates. The fireball went out over the Kuru keeper. The westernmost observation of the object came from Roland Blomqvist , who observed the phenomenon at M / S Amore in the Stockholm archipelago. (Photo by Esko Lyytinen)

The braking of the rocket phase was visible in the Finnish sky

22.2. SpaceX's latest Falcon 9 was launched in the United States. The Rocket Phase II braking was carried out at an altitude of about 490 kilometers near southern Norway. The progress of the second phase, with its brake fuel and fuel clouds, was wonderfully visible all the way to Finland . Dozens of sightings of the incident soon came to the fore, but with bad luck, Ursa's server iron broke down later that evening.

The Finn spotted Elon Musk in the car's space

11.2. Finnish star enthusiast Markku Nissinen has managed to spot Elon Musk in the space of the Tesla Roadster car. The observation has been made using a telescope over the internet located in Siding Spring, Australia. The Tesla Roadster ended up in space with SpaceX’s successful first launch of the Falcon Heavy launch vehicle .

Fireball over Latvia towards Gotland

5.2. On Monday at 20.53, a bright fireball was spotted again in southern Finland. Observations of the event have already arrived in 2 hours at more than 200 Sky Watchers. According to the modeling of Ursa's fireball working group Esko Lyytinen , the piece arrived in the Earth's atmosphere above the Curonian Spit of Latvia and progressed towards North Gotland. The meteoroid burned out completely in the atmosphere above the Baltic Sea. The temporal proximity to yesterday’s fireball off the Swedish coast is a coincidence.

Sunday night's fireball ended over the Baltic Sea

4.2. at 7.04 pm On Sunday evening, a bright fireball flew southwest of Finland. More than 200 observations of the phenomenon have arrived in Taivaanvahti, mainly from southern Finland (see up-to-date map ). The incident was also observed in Sweden. The fireball flight has focused over the Baltic Sea south of Stockholm. Meteorites that may have survived the fireball were lost to the sea. You can report your own observations using the fireball form .

31.1. The moon darkened in eastern and northern Finland

31.1. The partial phase of the lunar eclipse was left behind clouds in many places on the south and west coasts. In eastern and northern Finland, blackout bongers were more successful ( map ). More about the eclipse on Ursa's website . Observations of lunar eclipses are collected using an eclipse form , entitled ‘complete lunar eclipse’. Eclipse behind the clouds can also be reported under the heading ‘eclipse maximum behind the clouds’. Photo by Jussi Koponen.

Great ice mist in different parts of Finland

9.1.-12.1. There have been some great halo plays locally in recent days. In a couple of cases, a halorarity called the upper convex Parry’s arc has been magnificently formed. The attached play was discovered in Ruokolahti on 12.1. Päivi Alho-Puhakka . Another example is Rauno Pitkäniemi's observation 11.1. In Jämsä, whose pictures show, as two overlapping V- figures, the very sharp-edged upper convex arch of Parry and the 22-degree overhanging arch.

Between clear starry sky objects

7.-9.1. In recent days, it has been clear from time to time. Observations have also been made in the Sky Watch about objects from such a deep sky and the solar system. Archives have also been excavated and previously described space objects have been processed, as exemplified by Tero Hirvikoski's (Ursa, Western Finland) image of IC 1975 published today. Harri Kiiskinen from Sirius in Jyväskylä followed ( gif animation) telescope comet Heinze .

Tuesday morning's fireball ended over the Gulf of Bothnia

9.1. At 8.08 a great fireball flew in the Finnish sky. About 75 observations of the incident have arrived in the Sky Guard. Most of the observations are from southwestern Finland, but the phenomenon was visible all the way to Lapland (see an up-to-date map ). According to the fireball working group Esko Lyytinen , the song has burned out over the Gulf of Bothnia . Tampere's Ursan Jouni Raunio and Jarno Paananen published an animation about a fireball in Taivaanvahti (photo). Record your findings on the fireball form .
