Rare halos

2.12.2021 at 11.30 - 13.30 - Juva (IV)
Petri Martikainen, Ursa (Itä-Suomi)

The almost clear and calm frosty day drove the halo chaser to the outskirts of Hasamäki again in the hope of ice fog. Frost readings varied between 15 and 22 degrees depending on location. At Hasamäki, the scenery was completely obscured, but it seemed that the formation of crystals was weak. The fog was only close to the ground in a layer about 30-35 meters thick, and when the Sun was partly behind the clouds, the halosoot was modest. The icy mist was released by the drone, however, the moderate sub-side suns and the lower sun. There were also basic hugs in the upper clouds. The main picture ...

Landscape image of a planet

For a long time clear skies at sunset. The planets shone in a row at dusk, from left to right Jupiter, Saturn, and Venus. In the second picture, a compilation of them as they were drawn on a memory card in a Nikon super zoom pin (2000mm). The exposure times of the planets ranged from 1 / 2s to 1 / 30s. Planet images are unprocessed and crop as much.

Rare halos

28.11.2021 at 22.20 - 00.30 - Juva (IV)
Petri Martikainen, Ursa (Itä-Suomi)

The wind calmed down and the weather became clearer during the evening, so I went to see if there was any ice mist made by snow cannons near Hasamäki. It was about 12 degrees below zero. This time I didn’t have to be disappointed, I immediately hit the right place. The fog was dense and the stars shone through the fog in the sky. It was a great atmosphere and the halos were quite spectacular, the Schulthesses and ala-Kerni, which flashed in the full sky for a while, look better. I managed to shoot in the first place for a good while before the wind turned and took the fog away (Figures 1-6). T...

Light pillars

28.11.2021 at 21.50 - 22.00 - Juva (II)
Petri Martikainen, Ursa (Itä-Suomi)

I decided to check the northern lights situation with the camera when I was leaving for the cannon mists in Hasamäki in the evening. The sky was clear for a long time, but there was some cloudiness to the north. No northern lights were visible in the pictures, but one bright pillar of artificial light caught my attention. I took a few pictures of it. The light source was the greenhouses of Turakkala Garden, which is 17.0 km from the scene. To the right of the brightest pillar were a couple of dimmer pillars, but their source is harder to locate. There could be some 5-way lights at about the sa...

Several halo forms

Petri Martikainen, Ursa (Itä-Suomi)

For a long time, even a small halon in the sky behind a cloudy cloud curtain. The main image is a single image, the second is a stack of 40 images, and the third is still bg-processed. Stacking and processing did not bring out more shapes.

A modest backdrop in the afternoon. In the main picture, a stack of 8 images over a period of 4 minutes, followed by an unprocessed image from the stack. Marker tags also show the side sun a little earlier. Stacking did not bring more shapes compared to visual observation.

A side sun visible for a moment in the aircraft's abutment.

Several halo forms

Petri Martikainen, Ursa (Itä-Suomi)

Again, one must marvel at the power of the stack and the treatments, as that many other forms were found in that afternoon in the barely distinguished basic rinkula halo with the naked eye. Main image: first image of the stack at 15:48 (raw). Figure 2: Stack of 20 images at 15: 48-15: 54 (2x usm). Figure 3: same as the previous one, with the addition of bg processing.

Several halo forms

Petri Martikainen, Ursa (Itä-Suomi)

Evening halos. A muzzled backpack was visible for a while, and a worthy mash of 56 pictures accumulated in the stack. Not even handling it shed with certainty like 22r and sairs. In some sub-stacks, the reference to 46r was also very weak, and even in these pictures you can see something like a 9 ° ring (Artea?), But let it go unmarked. Even with the naked eye, those saints did not stand out. The main image is a stack of 56 images at 20: 11-20: 32 (3xusm), the second same in black and white and the third the first image in the stack without processing.

Rare halos

Petri Martikainen, Ursa (Itä-Suomi)

A nice haloshow in the light of the moon struck strangely after a long relentless season. I put the camera to capture the stack as soon as I got home from things. Zykki and 120 ° saur also shone brightly in the sky for a while, but the latter in particular faded away really quickly. Fortunately, it had barely fit in the camera's field of view. After that, I went to another camera to take pictures of the whole sky, but the best moment had already passed. Even the northern lights seemed to stick to the full sky. The main image is a gif animation from 9:32 pm to 10:02 pm, images of unprocesse...

Glory on air

23.9.2021 at 05.15 - 05.45 - Juva (III)
Petri Martikainen, Ursa (Itä-Suomi)

I woke up at five in the morning and went hunting with a drone on the Moon. The attempt of the previous morning had crashed to the rocks right from the start, when the drone refused to ascend, but demanded that the compass be calibrated. Well, I couldn't do it in the dark without a manual. Fortunately, the trouble later recovered on its own. This time there were no problems with the drone, but the dilemma was to find a decent fog. I set off to drive to the destination I was thinking about in advance. Already a couple of miles away was the first fog ferry over the road. I stopped at it and ...

Afternoon bag. It seemed like there was something right outside the base ring too, so I made a bigger stack, but that didn’t make it any clearer. Maybe just Artea. Unprocessed single image as main image, second processed (2xusm, bg) stack of 77 images at 14: 02-14: 15. Only 22r was visible to the naked eye, 46r was also found in the stack. In addition, weak side suns and pillars stood out in the other stacks.

The perimeter of the full moon described along with the ringing of the pearl owls. The early evening was calm and quite clear, meaning good conditions for both admiring the Moon and catching owls. In the bonus image, the Moon, which is partly behind the cloud. Two helmers received rings.

Several halo forms

10.9.2021 at 18.00 - 19.00 - Juva (II)
Petri Martikainen, Ursa (Itä-Suomi)

The first halos of the day were the side suns appearing on the setting sun from the evening moon. I then photographed them in a stack and gradually more shapes began to accumulate in the sky. First 22r and then also 22ys. The pillars were also visible. At half past seven on the right, a piece of 46 upside down stood out for a moment with the naked eye, but then it remained. Another 46r and a zykki were found in the stacks. The main picture is a stack of 50 pictures at 18: 28-18: 33 (2xusm, bg), the second one in the same color (3xusm) and the third one unprocessed picture from the stack. The f...

The only halo of the day, the left side sun. There was no need to take any more pictures today as the sky went into the cloud and it started to rain.

Afternoon halos picked up between the clouds. Quite a lot of stacks were taken, but nothing rarer was found in them. The naked eye missed hr and 46r. Main Image: A stack of 16 images from 2:38 pm to 2:40 pm double-tapered. Figure 2: Unprocessed single image of the stack. Figure 3. Stack of 20 images at 14: 56-14: 59 (2xusm, bg). Figure 4.

Fogbow

Petri Martikainen, Ursa (Itä-Suomi)

I have been waiting for these morning fogs floating on the lake for a long time and earnestly since I got the drone. Today, the wait was finally rewarded when the morning was calm and only a couple of degrees warm. The mist layer was a low mattress less than 50 meters thick above Lake Saimaa. Seen from above, it was very uneven. At very low he didn't dare fly over Pacific Lake so that the helicopter wouldn't mash into the lake. These images now show at least the nebula, the glory, the rays of fog, and the perimeter of the sun reflected from the water in the fog. With the exception of t...
