I'm going to take a guess not backed up by any mathematics - to be that close to a black hole, it would have to be well within the Roche limit and get torn apart. Plus, I'd wager they'd be able to tell if it was eclipsed by the black hole at all.

Plus a very visible Doppler effect. We know many stars orbiting neutron stars or blackholes because the Doppler effect, indicates that it's moving fast around something that we can't see.
