Orb-of-light UFO spotted over Dome of Rock, Jerusalem

It could be dismissed as a hoax, except, the same footage was shot in two different angles by two different unrelated people. The first thing that comes to my mind is, what are these "orbs" made of? Surely, this one is not the first of its kind. I've previously linked a video of it titled "Milkhill UFO incident" followed by another one seemingly making crop circles over a field.

"Orb" UFO's have also made an appearance in the famous Rendlesham (England) incident in 1980.
