Further Description of Sighting: I was looking outside, and then I saw a circular object hovering in the sky. I got my wife outside, and she saw it too. Our dog started barking, and it got windier for a few seconds, like it was going to land, but then it disappeared behind a cloud, and it was gone by the time the cloud passed.
