MDM Observatory 2.4m Telescope Observer's Report for 2002 Jun 11

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

Instrument: modspec

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

Seeing and Weather:
   Beg: Seeing 1.5 arcsec, Patchy Clouds, Winds Light & Variable
   Mid: Seeing 1 arcsec, Clear, Winds Light & Variable
   End: Seeing 1 arcsec, Patchy Clouds, Winds Light & Variable

Observing Summary:

Time series spectroscopy of cataclysmic binaries.  Weather
was mostly clear through the night, a little cloud, suddenly
heavy after AM twilight.  RA tracking slipped slightly around 
5hr E on one object, but the drive didn't squeal and the 
slippage was small enough to guide out by hand.  Otherwise 
trouble-free.
