Girl friend and I watching super moon, saw a wobbling star which was moving up, down and slightly to each side, then would remain still.Myself and my girlfriend were at Mooneys Bay Park, on top of a hill, watching the super moon around 21:00 last night. I happened to glance up at a star above the moon and noticed it was moving slightly. I know what a satellite looks like and it was not a satellite. This "star" was moving up, down and slightly from side to side. It remained in the same area of sky for the duration of us watching it. It seemed to follow the same pattern of moving up, then down, and then would remain still for a few seconds. Both of us could see it moving at the same time. We watched it for about 40 minutes before leaving. I kept looking up at it and could see it for about another 30 minutes or so, and then lost site of it.
