Russian Cloud Anomaly?

"Theories range from it being an alien mothership, proof of Russian weather modification technology - a weather weapon - or even a sign of the end of the world."

But meteorologists rejected theories of the supernatural calling it an optical effect.

"If you look closer, you can see sun rays coming through that cloud. Most likely, the sun was setting when the video was being made."
