MDM Trouble Report for 2002 Oct 24

Telescope: 2.4m
Observer(s): John Thorstensen (Dartmouth)
Instrument: Echelle direct

Problem(s) Encountered:
The telescope was tracking and guiding a target normally 
when the dome started rotating slowly, like it does when it
makes a fine adjustment.  However, instead of stopping, 
it just kept on a-going, eventually making a nearly complete
circuit.  I hit the xtcs window red  stop  button (not the 
hardware stop on the black panel) to no effect -- eventually
it just sort of woke up and realized where it was.  I recall
this happening to me before a couple times, maybe last night
as well, but I don't think I've documented it.  Lost almost
no time, luckily I was close enough to the zenith so as not
to lose the guide star entirely.  Lost a lotta light, though.
