Ok, so last night I used shorter individual runs with the idea that I could look for cloud features and maybe make an animation if I found anything.
Well, I found lots of features! Here's the GIF animation showing 3 frames. This is red channel data only. The times given are the centre of each run - the runs were 3 minutes each.
The animation is 214kb, too large to upload, so here's a link:
