We don't really notice cloud's motion from space. On planet's surface we do and we'll do more in 3.12 because of the new cloud's shadow.
Yeah that was kind of my question. So these clouds do actually cast live shadows on the surface? Or it's just an effect seen from space?
I think for science you need to fly down in your Aurora and chase some cloud shadows Ant
(I'd call for a video, but that always ends up with people actually posting SC videos here. Which can be quite dull :/)
