MDM Trouble Report for 2002 Oct 26

Telescope: 2.4m
Observer(s): John Thorstensen (Dartmouth)
Instrument: modspec+echelle

Problem(s) Encountered:
The telescope is singing again --
while tracking it occasionally emits a rhythmic, high-pitched 
tone, the pitch being nearly constant.  Also, at HA 2E16 and
dec -16, the tracking failed -- the stars (and HA readout)
jumped back and forth by about 5 sec of time.  The telescope 
was not squealing at the time.  I was just finishing that 
target anyway, so I resolved the problem by slewing to the 
next target (slew worked fine) and the telescope worked normally
for the rest of the night.
