Several bright halo forms

9.12.2022 at 17.15 - 17.20 - Porvoo (III)
Jan Blomqvist

When leaving Kotoo, you could see light pillars, some quite high. The street lights were also reflected up and down. When the moon emerged from behind the forest line, a very clear cross pattern (horizontally and vertically) was visible. A little further away, you could see the halos according to the pictures. In the same area, a strong inversion problem caused fog on the ground about an hour earlier. There is also a skiing center nearby with snow in progress. There are a few guesses about birth. More pictures (taken with a phone, some in raw format) are available, e.g. by e-mail, if someone w...

The day turned out to be quite foggy, and in the morning it was quite cloudy. A hint of the 22° tire could already be distinguished at that stage, and after the weather cleared up a few days later, it stood out better. The first picture in the countries of one, the second a little before eleven.

After a cloudy period that seemed like forever, finally a clear and sunny day! After coming from the store, I noticed clouds of color in the dock area of Hietalahti. I don't know about the time duration, as I couldn't follow. However - a new observation after a long time!

Jani Poikela, Ursa (Etelä-Suomi)

When I arrived from lunch, a fine ice fog had appeared in the yard of the workplace. Among the fog, ice crystals also stood out in the sunlight and the 22 degree ring and apparently also the Moilanen arch became visible.

A short-lived arc was visible when the fog clouds dissipated from a suitable point.

The 22r of the moon stood out visually. With BR, you could show the attracted tire a little better.

I'm hearing 22r right now, I'll have to watch for a while to see if other halos come there

Several halo forms

Timo Nevala, Ursa (Länsi-Suomi)

The 22° ring appeared around the Moon for hours, sometimes dim, sometimes really dim. The upper part of the ring was so much brighter than the rest of the ring that I interpreted it as an overhead arc. In the second picture, right next to the Moon, Mars also stands out.

With 200mm, several dark nebulae of the Kotka constellation could be seen with the Fuji lens. Barnard's E Nebula, i.e. B 142 and B 143, are the most familiar on the left.

Moon and Uranus

Matti Helin, Ursa (Länsi-Suomi)

The moon was supposed to cover Uranus on December 5. around 19:00. I took a few pictures after 5 in the evening, when a patch of clouds was already forming in the sky. Luckily I took it, because at the time of the eclipse the sky was completely covered. to the clouds. In the pictures, Uranus was faintly visible, but still clear. The blue color is striking in the pictures, it has not been emphasized at all. The triple image is from Stellarium, at 17:34.

Throughout the morning, you could distinguish 22 rings, sometimes better and sometimes worse. In the second picture, one of the more than a hundred light flowers on the riverbank, which for a few days enchanted passers-by in the dark.

They are already getting very close to each other. Unfortunately, the snowfall starts at 04. Now OsmoAction is knocking a timelapse of that haloing. Gotta get up early in the morning to check the weather.

In the corners of the midday, you could momentarily distinguish a very non-existent 22° from behind the ring-like lower clouds.
