Petri Martikainen, Ursa (Itä-Suomi)
The faint halos of the hot day appeared in the sky in the midday countries. I was in town on business, so the documentation was initially limited to a cell phone snap I took on the way home (picture 6). It shows 23 slaika. At home, I immediately lit the pile on the fire, even though there was almost nothing to distinguish from the cloud cover (picture 3). From the first 120 images, more pyramidal halos seemed to come off in the stack, so I took another stack of 120 and 300 images. Unfortunately, the halos were so weak that certain shapes could not be identified even with hard processing. 23yparh, 9r, 20r, 22r, 35r, 46r and sauris can be separated from there quite painlessly, but 18r and 23r-24r ties remain unclear. 13r could also be involved. Illemma also found zyk in the stacks, I'll mark it for tags as well.
