Really bad luck Ron!  Thanks to your phone call on Friday night, I made
the effort to observe the Saturday morning transit of #24763, 97-15C.
It rose in the NNW bang on track, and only about 3 secs late (thanks,
Alan!).  At 18 deg el it was about mag +6.5 steady.  At culmination, 36
deg el in the NE, it reached +5.2 steady.

For the record, here are three positions:
UT 10:28:01.18  RA 08:31.5 Dec +67:19 (2000.0) 
UT 10:28:48.24  RA 00:41.4 Dec +56:32 (2000.0) 
UT 10:28:53.83  RA 00:15.1 Dec +48:01 (2000.0) 

At UT 10:14, the Mir/Shuttle combo reached mag -1.
