In case you haven't seen it yet, at 1:19 there is a very intriguing video of an UFO flying over the moon:
My guess would be that it is not three UFOs as suspected, but only one and the other two are shadows with one coming from the sun and the other one is from earth. With knowing the strength of the telescope and the distances to earth/sun, it would be possible to calculate the size of the craft and its distance to the moon surface. Well, others might be able to do so, I lack the skills :-)
