Visibility IV / V
Kind of lucky. In Illansuu, during a routine check, I noticed a weak zyk in a fairly cloudless sky. I set the camera to shooting readiness, but I had to realize that the zykki had already gone. However, just for fun, I put a stack of 120 photos on fire. My expectations were zero, but I still checked what was being filmed. At first nothing, but then very sharp halos drawn by a passing cloud. In the end, 77 pictures ended up in the pile. Parry was hiding there. In a timelapse made from a stack of images, you can sort of distinguish halos in the sky.
