MDM Trouble Report for 2002 Sep 21

Telescope: 1.3m
Observer(s): DePoy & Marshall (Ohio State)
Instrument: Echelle

Problem(s) Encountered:
When we first started observing, the guider would move the guide
star out of the box every 5 minutes or so.  The frequency of 
malfunction seemed to decrease in about an hour, though after 
two hours we still have to bring the star back into the box 
manually every 15 minutes or so.  It seems to be worse
right after a move to a new telescope position.  The star 
mostly moves out to the north, but sometimes to the south also.
The east-west tracking seems to be fine.
