Rare halos

Tero Sipinen, Ursa (Etelä-Suomi)

I was thinking of driving around the villages to see if there were artificial light poles anywhere. The expectations weren't very high since it was probably only ten degrees below zero, but I noticed as soon as I came out that I didn't have to remain observant when a faint halo ring was visible on the Moon. Just to be sure, I took a couple of pictures from the backyard. After almost a couple of hours of "spinning", not a pillar of a pillar could be seen, and there was no longer any halo on the Moon, even though I put it in park to check the situation. Quite ironically, Kuu's halo r...

The pyramid halos of the previous night continued when a faint ring began to appear around the setting Sun. No clear shapes could be seen with the naked eye, but there was something in the pile. The first 120 pictures could be taken without major interference from lower clouds, after that the stacks taken until sunset were almost unusable as the cloud cover increased. The wind was blowing from the south (the temperature was barely on the positive side), which might have something to do with the appearance of pyramid holes so early. Pino revealed a reasonably good pyre show, where you could com...

A rainbow began to form in the sky, which was joined by bright halos.

Petri Martikainen, Ursa (Itä-Suomi)

The evening was quite clear and the Moon shone bright in the sky, disturbing the observation of the comet. In the lands of Iltakymme, weak clouds began to gather around the Moon, and with the side eye, they could be seen as rings. I took a stack of a hundred pictures and checked the situation at the computer. Somewhat unexpectedly, the pictures revealed a fire, so I took the camera back to work. In the first stack of hundred pictures, there seems to be a 23° slaika and an 18° ring and parhelias in addition to the basic ring. In the latter set, in addition to the basic ring and the upper side r...

Jari Luomanen, Ursa (Länsi-Suomi)

Mikkilä and I were team hunting for a long time. The predictions promised a slab crystal inferno, and we got something of a kind. First there was a good set with lower side suns and Lowitzes. In addition to the concave and convex Lowitz shape, a divergent tail (i.e. caused by non-parallel light) seems to come from the lower side suns, and in the same pictures there is of course also a so-called a superlamp (i.e. relative to the divergent light of the upper sun) as an extension of the pillar.* The images of the Lowitz phase (the two images where the lower side suns are sharp) have some funny ju...

Marko Mikkilä

Years of dreaming about a halo observation trip came true last Saturday at short notice. The forecast showed excellent weather for Himos and at the same time the full moon was beautiful in the sky. So let's go. Jari Luomanen and I booked a cottage as a base for the halo trip. The evening started around half past seven when we set out to explore the area. The first blow resulted in a return trip to the cabin when someone forgot Blokker at the cabin. (Me) Around eight in the evening it started to happen. Ice fog formed in an area of a few kilometers and we found a good dark field where we fi...

Weak/variable cloudiness and a light drizzle of snow in Nilsiä was caused by these things. It lasted about half an hour, slowly getting worse.

Jani Päiväniemi, Ursa (Pohjois-Suomi)

When I came to work, I went to photograph Juhannuskallio and went on a gondola ride and photographed the changes in the ice fog from the window. Moilanen's arc was visible from time to time and sometimes there was also a glimpse of a parry. It's as if the death had momentarily been visible on the 46' overhead.

Antti Taskinen, Joensuun Seulaset

I was looking at the scenery from Akka-Koli when I noticed this pillar of light under the sun. It seems to be the lower sun. The lower side suns also stood out, especially the one on the left. Ice crystals floated in the air for a few minutes.

During the day, there was clear and good ice fog in the air. It seemed that Moila was also involved. Beautiful winter day, freezing in the lowlands 30 degrees in the morning.
