UFO...cloud?

  This bizarre halo cloud photo was taken from a cell phone in Moscow just a few days ago.  It's gotta be the weirdest cloud I have ever seen.  Some people are calling it a UFO, but its obviously a cloud.  It's just really strange and it makes you wonder what would cause a cloud to look like that?
An official spokesperson for Moscow's weather department said, "Several fronts have been passing through Moscow recently, there was an intrusion of the Arctic air too, the sun was shining from the west — this is how the effect was produced."
Still, that seems like a decent explanation, but can it be the only explanation?
Kind of reminds me of the Goatse Cloud.  Hahaha.

Goatse

Anyway, overall I think the whole thing is just... interesting.  It's a crazy looking cloud, and thats all I can say about that.  ;)
Also, here the video clip that goes along with the first picture of the cloud.
