I don’t know what this could be, but it is a very weird cloud formation in Moscow,  Russia. Some say it is something that was left behind by a UFO. Others think that it is some sort of remains from a dimensional portal. Yet, others think that it was caused by HAARP a top secret program that the US is doing in Alaska. What ever this thing is, it sure is strange. Maybe someone out there can explain to me what we see in this video.
