Enjoy this time lapse of a lenticular cloud

This video via Dakota Smith and Jesse Ferrell shows a lenticular cloud, which is a disc like cloud that is formed above an obstruction, thanks to the change in relative humidity on the lee side of the mountain (or whatever obstruction you find the cloud formed by). They have been confused for flying saucers before, and surely you can see why, looking at the cloud form and reform in the video above!
