MDM Trouble Report for 2002 Nov 24

Telescope: 2.4m
Observer(s): Jules Halpern (Columbia U.)
Instrument: Echelle CCD Direct

Problem(s) Encountered:
After observing for about 10 minutes at H.A. -3.5, Dec. +29,
tracking started slipping.  This was at 21:30 hours local time.
Looked at the R.A. drive for a few minutes, but couldn't figure
out what to do.  Eventually got around the problem by observing
a different target. If this occurs mostly in the east, as seems
to be the case from the history of trouble reports, then it's
not a big problem for me tomorrow because my most important
targets are in the west or overhead.  Problem has not recurred
since then.  It's now 03:00 hours local time.  I note that it is
5 deg C colder tonight than the past two nights.
