Black UFO Moving Slowly Over East London May 19 2016, Video, UFO Sighting News.

Date of sighting:  May 19, 2016
Location of sighting: East London, England

This UFO was seen over England last week and as it passes in front of a cloud the blackness of its color stands out. The UFO is turning slowly as it moves and this is why its shape changes every few seconds. London is a hotspot of UFO activity so this comes a no surprise.
