Last night I was waiting for Saturn to get high enough to image and decided to scan the moon. In doing that I found this shadow slowly hovering over the surface. What is this?

Prior to the image above, i first saw this shadow but its moving faster and the moon was low and i had just started adjusting focus and color so its really hard to make out

Plane?

My thought is ballon or satellite? Lots of space junk out there. Perhaps a distant, out of focus small plane, but I don’t see any blinking lights. Currently it’s a UFO!

Most likely just an "identifiable"  flying object   IFO.

If this thread move into UFO discussion it will be locked for going off topic.

Le ballon rouge. It's been missing for some time now (1956).

My guess is a balloon of some type.   It is moving too slow for a satellite, unless it is near geosynchronous orbit, and then it would be very very tiny.  A balloon 1 to few feet diameter is about the right size.  Very cool video!

Very nice! Almost certainly a balloon in the earth's atmosphere.    Tom

A balloon is a good candidate. I see roughly round shadows moving across the Moon at times and have always figured they were escaped balloons. I also see birds often, although they are usually close enough that they're obviously flying birds. Especially common during spring and fall migration. If one was higher up it might move as slowly as your shadow and not show enough detail to be identified.

 

See similar things when solar observing. 

 

Clear skies, Alan

I have to say I find both the speed of the object and its apparent size to be at conflict, given the magnification against the surface of the moon. I still don’t think we have this figured out…

Sadly the sky is full of junk now. When I was a kid (in the 60's) it was amazing to see a satellite. Not any more.

Very interesting... it doesn't look balloon shaped to me; it looks like it has an irregular shape and is tumbling end over end. Could it be something in orbit around the earth, or moon? Space junk? Can't tell the size. Very cool, thanks for posting!

I thought it looked like it might be tumbling, too, but I wasn't sure if that might not just be the jumpiness of the magnification.
