Location of sighting: International Space Station
Now this shadow really looks like a very large craft is moving behind the space station, blocking out the sun. I have looked at the video over and over again and just can't find any explanation for it other than something large was on the other side of the ISS and casted its shadow onto Earths atmosphere upper layer. Very cool, and if its a UFO...very freaking big. Awesome catch.
