MDM Observatory 2.4m Telescope Observer's Report for 2003 Feb 01

Observer(s): Thorstensen
Institution(s): Dartmouth

Instrument: Modspec + echelle

Worked for 13 hours (all night)
Conditions were Non-Photometric most of the night.
Problems were encountered, see the separate trouble report for details.

Seeing and Weather:
   Beg: Seeing 1 arcsec, Cirrus, Winds Moderate
   Mid: Seeing 1.5 arcsec, Cirrus, Winds Moderate
   End: Seeing 1.5+ arcsec, Patchy Clouds, Winds High

Observing Summary:

Quite cirrusy at sunset, and probably lots of cirrus all night,
heavier at times toward morning.  Wind picked up during the
night, a few gusts exceeded 30 mph, but never in real danger
of closing.  Seeing was fairly good at first and then 
deteriorated, but wasn't wretched as one would expect.  Trivial
problem: guider computer froze up for no apparent reason, 
wouldn't respond to keyboard (even ctrl-alt-delete).  Turned
it off and back on, which cured the problem.  No time lost.
