Next one puzzles me a bit. I took this picture in a split second while distracted by my cat who wanted to do dangerous things by climbing out the window I was hanging out. I just thought it was iridescence but later I saw the regular pattern of colors with reds up and blues low. No CZA for sure for it was too low. It still might be iridescence but a small segment of a 22 degrees halo is also possible for it is taken with 400 mm. Wish I had more peace at the moment I spotted this to check the circumstances better. When the cat left the colors were also left.
