Visibility IV / V
Just rarities in the sky. The day was hot, the highest temperature was over 30 degrees and the wind was blowing from the southeast. In the afternoon, a faint arc just started to stand out over the Sun, so I took the camera to take a picture. At first, only the modest 23 slaika stuck to the stacks, but a little later other shapes also joined. A bit strangely, the stacks do not show any usual halo shapes, but only pyramids and even clear pyramidal sides. Based on the comparisons, the outermost ring is mostly a 23 degree ring. The best stage lasted only about 20 minutes. Marko Riikonen has once analyzed a very similar show .
