On July 2, 2011, a group of glowing orbs was seen floating over an area of Moscow, and on a video that captured them, they appear to change back and forth from white to orange.

It's yet another UFO video that has shown up on the Internet for all to see.

Problem is, as in most of these mini sky shows, it's difficult to prove whether an enthusiastic videographer has captured, finally, a true alien visitation to Earth, or something more mundane, like simple Chinese lanterns (which are often misidentified UFOs).

In this case, as a jet reportedly flew near the aerial objects, all of them except one turned off their lights. One online blogger wrote: "This proves the orbs thought they may be fired upon, so the majority of them cloaked."
