30.5. Markku Ruonala tells in his rainbow observation on 28.5. the supply of the phenomenon has been on the cards this year. Skywarden's statistics agree. From 2012, in the period from 1 January to 28 May, rainbow in Finland has been seen on maximum of 20 days (2016), minimum of 10 days (2013 and 2019). This year only 8 rainbow days were reported on this period.

Subsun from wingsuiting jump

28.5. Glories and fogbows are the basic imagery of wingsuiting. A rarer prop is represented by the bright subsun that Vesa Toropainen saw above Utti on 27 May. This was made possible by the jump taking place over a crystal cloud that had been left over by a dead rain shower cloud.

The most summery aurora borealis on July 2000

27.5. Jorma Koski left a report about the aurora borealis he saw on 16.7.2000 in Porvoo. At the time the pictures were published in SpaceWeather on the same day. Their occurrence 596 hours from the summer solstice (according to 1:00 a.m.) single-handedly improves "the most summery" record for the Finnish northern lights in Skywarden, which has been 912 hours (July 29, 2016). The aurora were of the most powerful G5 category. "My head spinned like a top", Koski says.

The attached screenshots are from Juha-Matti Kaataja's car camera video. Juha Ala-aho in Vaasa didn't manage to photograph the fireball, but captured its smoke trail with a mobile phone. "The smoke was visible for two minutes before it completely dissipated," he says.

The wait of about ten years is finally over and in what weather! I was feeding the cats and happened to look through the window. The plane, brightly lit by the sun, drew a streak across the sky. Pretty. Within a few seconds I realized that it seems to be heading straight for the moon! Fortunately, the camera bag was next to me, so the telephoto lens was on, quick adjustments to the camera and out the door. I focused on the plane and followed it for maybe a good ten seconds. When the plane then seemed to be going straight over the Moon, I couldn't believe my luck! In the end, the machine wa...

The pine owls now effectively. The three zones separated the eyes well even with sunglasses. Nicely, the intensity varies when you follow a longer time through the viewfinder. The third zone really emerges from time to time and disappears just as quickly. Windy weather probably enhances that phenomenon.

I was in the garden in a bunch of weeds when I looked up into the eastern sky and saw a convex halo down, out of the direction of the sun.

There have been few Rainbows for this year, but now a really beautiful one was available. The conditions for visibility were really good, the sky slowly opened from the direction of the sunset and at the same time the rain with its large drops was still enough.

In the afternoon, widespread upper cloud and halos appeared starting at 22ys. The horizon ring was completely visible for a short time, but there was scattered lower cloud in the sky, which made it difficult to see a possible brightening of the 120-degree side sun.

Timo Nevala, Ursa (Länsi-Suomi)

The halos of the day were characterized by speed. A single halo could appear and fade away in just a few minutes. Only the 22° tire remained visible for a long time in the evening. In fact, that also appeared a few times in the afternoon in the same way for a few minutes. All the other halos of the day were dim except the side sun, which was downright eye-catchingly bright, for a while. Main image 1 is the unprocessed image at 19:55. At that time, the upper part of the 22° tire looked somehow strange: unusually thick and unclear, as if there was something else there, but the eyes could not tel...
