Well, since we don't know the exact time, we can't say for certain
where it would lie in the Clarke belt. Someone else pointed out that
geosats 21019, 15235, and 14133 would be in the vicinity about 20:18.
The latter two are SBS4 and Anik C2, so I doubt if they're flashing.
However, 21019 is Blok-DM2, which is a "drifter", and hence a
