Here are two time lapses I had done a few months ago.
I think they’re a bit interesting because in the first one below, I had caught a 22 degree halo with a sun dog in it, and in the second one you can see the shadows of clouds on top of lower clouds, as well as a holepunch cloud. Sadly I didn’t catch it forming, but still nifty to have caught it.
The first one with sun dog and 22 degree halo:

Never got a good shot of it as other clouds were always in front of it.

Eventually I’ll put up the code I’ve developed that generates these time lapses with their details.
