Glowing UFO Seen Over Moscow Causes Storm, July 27, 2015, UFO Sighting News.
Location of sighting: Moscow, Russia
This glowing orb was buzzing silently around the tree tops near some buildings in Moscow. The eyewitnesses believe it to be ball lightning, but ball lightning is much smaller than this. Ball lighting is always just a few cm across. This UFO was about the size of a motorcycle. Ball lightning last for under one minute, this didn't die out, but instead lasted 15 minutes, then it flew away up into the clouds.
Look at the above screenshots and you will see different filtered versions of the orb. There is a second ring of light around the ball. This is new. This UFO flies like its alive and curious. When a girls scream is heard, it shoots upward and disappears into the clouds, as if the scream frightened it. Its self aware. I wonder, did the UFO cause the storm a few minutes later? I think so.
