I saw it too, but only for about a second at a time. The image seemed to 
clarify and the star was there, then it would be gone again.

Around midnight, Michael was helping me out by looking for M73 in his 
(much larger) scope, since I wasn't able to find it in mine. He said he 
saw something flash; I'd been looking through his telrad at the same time 
and I hadn't seen anything. He saw it again a few more times and then let 
me take a look: it was flashing about every 10 seconds and moving very 
slowly. When we first saw it it was between Albali and nu-Aquariae (near 
the Saturn nebula) and over the next 45 minutes or so it moved past nu 
towards Deneb Algedi at roughly 3-4 degrees per hour. I watched it in my 
binoculars until I left around 12:50.

I think it was Robert that pointed out that it was most likely space 
debris rotating once per 10 seconds. Considering how slowly it was moving, 
it must be in a very high orbit, or at least near the apogee of a higly 
elliptical one.
