And I captured it. The clouds were disappearing as the sun started to set, and after the sun disappeared it lit the clouds from below. A beautiful sight which only lasted for about 15 minutes. I made a time lapse video of the cloud movement from around 15:00 to 18:00. You can find the crappy quality version on youtube here (please rate it!), and the high quality version on my webspace here. Enjoy it while it lasts!
