MDM Observatory 2.4m Telescope Observer's Report for 2003 Jun 18

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

Instrument: echelle direct + 2in FW

Worked for 9 hours (all night)
Conditions were Photometric most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Beg: Seeing 1.5 arcsec, Clear, Winds Moderate
   Mid: Seeing 1.5 arcsec, Clear, Winds Light & Variable, seeing variable
   End: Seeing 1.0 arcsec, Clear, Winds Light & Variable

Observing Summary:

A good night, photometric but with variable seeing. Direct 
imaging of cataclysmic binaries for astrometry and ID work.

One minor glitch -- the ambient dome temperature reported by
the A/C control computer intermittently reads crazy values
(like -2000 Celsius).  If it persists long enough it can show
up on the history graph.  Also, following up on the coffee
maker, I think last night the power switch had somehow been 
turned off (though it was taped).  I'm still not entirely sure
the water is getting hot enough.

Changing to spectroscopy tomorrow.
