Only 78 days to Stein encounter ! I can't believe I forgot about this event.

Do we have any radar data indicating binary/satellite existence for any asteroid in this size range ?

Just wondering what the odds are for 'nother Dactyl type discovery. Would 200+ images for albedo study yield enough light curve data to rule out a satellite? Particularly one that was in an orbit inclined enough so that the satellite was never eclipsed or transited the primary.

I couldn't find any relevant radar data, but it appears see here that a moon has been likely ruled out for Steins.
