Visibility IV / V
I complained during the day that there is a good upper cloud but no crystal. Then after four a really bright 22° ring appeared in the sky quite unexpectedly. I took a few pictures from that place and that's it. The halo was almost completely lost in the quarter. I managed to photograph the pile as well and found more shapes there. By measuring the 9° ring, it matches so well that I mark it as well. There are 40 images in the stack and BR processing.
