Sue Worden reminded me that the tiles on the underside of the Shuttle
are black, which would make it much more likely that some observations
of the shuttle would be fainter than others -- white top ("dorsal") side 
down = bright; black bottom ("ventral") side down = faint!  Here are
some 
links to photos:
