Please click here to start the download of a time-lapse movie showing the evolution of this cloud!

I have been very lucky to get this picture. I was first intrigued by the odd shape of the cloud when I started my time-lapse movie. The picture was taken in Sherbrooke (Que.)

I lived a very long time in the Trois-Rivières region (aka Three River in the Quebec province of Canada) and I wasn't able to see many anvil-shaped clouds. However I've seen more than three of theses since I am in Sherbrooke.

I have put on top an actual picture of the Star Trek starship. Don't you think there is a good ressemblance?
