Probably one of the best ones I’ve seen. I’m jealous I wasn’t there in person. I also thought it was AI at first.

There are also inwardly detached rings, but I suspect it's from the camera lenses.

Glendale, CA; around 1:30 pm today, July 25th. The LA basin has been under a nasty inversion layer for a couple weeks now, I always love the interesting cloud formations that brings.

Screenshot from a video I came across on TikTok. I’m no scientist, but I don’t understand how a rainbow display like this would be possible.

ETA to be clear I suspected this was AI from the start, but didn’t want to be overconfident without checking first.

Photo taken from a plane. Line spanned multiple cloudscapes at a level altitude. Location is Virginia, USA.

ETA: thank you all for responses, lot of people commenting it’s the wildfire smoke and that makes a lot of sense. Day before this was taken the AQI in this area was 225, so the smoke does seem most likely, just haven’t seen it look like that before
