MDM Observatory 2.4m Telescope Observer's Report for 2003 Feb 02

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

Instrument: modspec + echelle

Worked for 10+ hours (all night)
Conditions were Photometric most of the night.
Problems were encountered, see the separate trouble report for details.

Seeing and Weather:
   Beg: Seeing 3 arcsec, Clear, Winds High
   Mid: Seeing 5 arcsec, Clear, Winds Moderate
   End: Seeing 1 arcsec, Clear, Winds Moderate

Observing Summary:

Nice and clear, but sharply colder - mirror warmer than
ambient, substantial wind, so mostly wretched seeing which
weirdly improved just in the last 2 hrs.  Had to
close early to catch a plane.  

Two problems: 1) CCD read failed at start, see  Feb 1  trouble;
 2) At very end, telescope tracking slipped at 2 47 E. Luckily
  I already had enough on that target anyway so I could just
   close up.  Before I did so I slewed out of the  jam  and 
   the tracking appeared normal again.  It is maybe 8 C cooler
    than it's been.
