MDM Trouble Report for 2002 Nov 15

Telescope: 2.4m
Observer(s): Zosia Krusberg (Dartmouth College)
Instrument: Echelle

Problem(s) Encountered:
Both tonight and last night the telescope has been giving off
strange high frequency noises (entirely irregular).  Yesterday
I thought it might have been related to the wind as the problem
only occurred while the telescope was pointed east (which was where
the wind was coming from).  However, tonight, even at times of
no wind, the same noise would be given off.  It appears to happen
whenever the telescope is at an hour angle between roughly -4 
and 0.  Both today and yesterday this noise was accompanied by a
drift in RA of about 10m, although on several occasions it would keep
drifting.  I checked in the dome to try to see where the noise
came from, but was unsuccessful.  Essentially, I was unable to
observe anything in that area of the sky and had to wait for the
objects to move out of the critical area.
