Well, if it's in the list, with a proper Standard Magnitude, then the
prediction programs will generate correct positions with correct
magnitude when it's at perigee. When it's not, the prediction programs
will correctly figure out that it falls below the cutoff magnitude,
and ignore it. Shouldn't the list contain all objects that are
SOMETIMES quite bright? 

What exactly IS this thing, anyway? And what are the parameters of
its orbit?
