Active aurora band

28.11.2021 at 22.30 - 02.30 - Valtimo (III)
Eero Karvinen

Pretty little northern lights show in a situation where there was a lot of plasma and Bz bounced properly to the minus. One substorm was seen, but another, the development of the morning night, was lost as a pseudo breakup and energy was lost in it. This event provided for the brightening of the arch stretched south without it spreading south and north. Pictures below. The third image below shows a false start. One small lunar halo also fit.

Remarkably bright side sun.

A fireball at night, as bright as a cresent moon

28.11.2021 at 06.58 - Vesanto (III)
Timo Kuhmonen, Ursa (Etelä-Suomi)

A bright fireball from Vesanto's camera. Watched from the video, the duration was 0.6sec. Fly down in the picture to the right, leaving behind a glowing old one for a while ...

One halo form

27.11.2021 at 09.30 - 11.00 - Saarijärvi, Lannevesi (I)
Tuomo Vilkkilä

There was a lot of glacial ice floating in the air, which made the rising sun a powerful pillar or halo. The halo phenomenon continued throughout the sunrise.

Quiet aurora arc

29.11.2021 at 00.05 - 00.10 - Rusko (II)
Mikko Peussa, Ursa (Länsi-Suomi)

Just as I got to the scene, the clouds started flying in front. However, statistical scraps are recovered here near Turku.

Active aurora band

28.11.2021 at 21.00 - 23.15 - Salla (III)
Dennis Lehtonen

Today there were great bright northern lights that covered about half the sky. Unfortunately, the clouds covered the other half of it and later both. The outside gauge showed -27 degrees and the camera's batteries are pretty weak, as they clot quickly. I didn't bother 100m beyond the backyard to leave.

Quiet aurora band

28.11.2021 at 22.38 - 22.46 - Kuusamo, Käylä (II)
Jani Päiväniemi, Ursa (Pohjois-Suomi)

For a long time, northern lights had to be seen when, due to the work, they had not been able to control and there was no weather. The nearest forest as a shooting area. It was pretty.

Several halo forms

Marko Myllyniemi, Lakeuden Ursa

The clouds in the morning showed 22r, a pillar of sunshine and 22ysk.

A fireball at night, brigter than the venus

28.11.2021 at 19.53 - Jyväskylä (III)
Harri Kiiskinen, Jyväskylän Sirius

This has presumably been quite bright as it is well visible through the clouds.

M45 and NGC 1499

26.11.2021 at 22.30 - 02.00 - Järvenpää (III)
Eemil Pietilä, Ursa (Etelä-Suomi)

I photographed this target pair through a 50mm lens. At first I was skeptical about the weather, but after 10pm the weather became clearer and I decided to put the camera to shoot. After a while, I realized that the camera battery was exhausted, so I replaced it with a new one. But it didn’t take long for me to come back again and this time the power bank battery was running low, so I went looking for a new one and found one. In order not to solve it with such small problems now, the fuses on the cake burned over the whole house, which meant that the laptop no longer received power outside and...

Light pillars

Minna Glad, Kuopion Saturnus

Quick shots of the artificial light pillars spotted along the way! -13 degrees below zero.

Light pillars

Kari Kauppinen

I woke up at night, it had a peeked outside gauge of frost seemed to be -18. I noticed the artificial light pillars at the same time. Outerwear on and off. I took pictures on my cell phone.

7354 Ishiguro

6.11.2021 at 20.52 - 21.13 - Orimattila, Artjärvi, Tähtikallio (I)
Kari Laihia, Eero Koivula, Olli-Pekka Joronen, Christos Oscar Kambiselis, Toni Veikkolainen, Veikko Mäkelä, Porin Karhunvartijat

The asteroid on the outer edge of the main zone of 7354 Ishiguro (1995 BR1,1976 UE11,1982 VV4,1982 XN4) was photographed on the second night of the November 2021 work. When we photographed the fish spiral galaxy NGC 488, this came into the picture like several other asteroids. The asteroid was discovered by the Japanese amateur astronomer Takao Kobayashi at the Oizumi Observatory on January 27, 1995. The asteroid is named after Masato Ishiguro (b. 1945) of the Japanese ALMA project manager (Atacama Large Millimeter / submillimeter Array).

Pentti Ketola, Ursa (Länsi-Suomi)

The clear frost on the morning of 28.11.2021 showed the moon quite nicely, so this time I had to take a picture with face focus.

Several halo forms

28.11.2021 at 10.45 - Vaasa (II)
Timo Alanko, Vaasan Andromeda

I raised Mavic for a small frost test (-15). Well done and preyed on a couple of halos at the same time. The first image is slightly tuned with Snapseed's HDR function. The second original.

Several halo forms

27.11.2021 at 13.15 - 14.15 - Pälkäne (II)
Sari Suonpää

While driving, I thought I could see the rainbow first and then the other end of the rainbow, but I don't think they are in the frost ... According to the car's meter, the frost was -8 degrees. I cursed into the large open field behind the Pälkäne ruined church, where all the splendor looked great! The side suns and the colors of the rainbow at them appeared very bright at times, and at times a little dimmer. I took pictures, but those colors corroded in the bright backlight and didn’t stand out in the picture. For about an hour I watched it, meaning the phenomenon was still in the sky...

Rare halos

27.11.2021 at 11.18 - Ylojarvi (IV)
Velipekka Soini

Aamun rekkulenkillä taivaalta löytyi tällainen halo-spektaakkeli. En ollut ennen nähnyt moista, niin piti tallentaa kännykkään. Kuva on otettu panorama-asetuksilla, koska muuten koko komeus ei mahtunut kuvaan.

Several halo forms

28.11.2021 at 05.00 - 06.00 - Mäntyharju (II)
Jukka Kytömäki

Halo phenomena to hear. Would 23 parchels be included. 1 = south. 2 = north. 3 = southwest. 4 = northeast. 5 = north. 6 = south. The halos disappeared after six.

Powerful artificial light pillars from riverside lamps. Freeze-16 C.

Light pillars

27.11.2021 at 17.14 - Kuusamo, Rukatunturi (II)
Jani Päiväniemi, Ursa (Pohjois-Suomi)

Sharp and pretty pillars were visible on the slopes in the evening. Snowmaking was not running over the weekend when the Nordic Opening Games were underway. It freezes at about 20 degrees.
