Dear CBAers,

I just wanted to scho Tom's remarks.  Over the next 1-3 weeks, we want to 
track this thing down to minimum light, and beyond.  Even a short run, or 
a snapshot, is fine if it's decently calibrated.  Best is a V filter, 
preferably with GSC 3656-1399 as a comparison. A different comparison star 
is OK, and unfiltered is OK too, as long as you clearly specify what comp 
you used.  Whether the star's light curve ever wiggles, we dunno (so far 
no) - but how it returns to minimum may well provide a nice test for a 
microlens hypothesis.

Of course, any earlier data would be mighty nice too!
