MDM Observatory 2.4m Telescope Observing Report for 2009 Aug 31

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

Instrument: echelle direct + Buckeye FW

Worked for 4 hours (off and on through the night)
Conditions were Mixed most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Clouds all night.
   Beg: Overcast, Winds Light & Variable
   Mid: Seeing 1+ arcsec, Patchy Clouds, Winds Moderate
   End: Seeing 1.5-3 arcsec, Patchy Clouds, Winds Moderate

Observing Summary:

Cloudy until about 11 PM, then a clear hole, then cloudy again, 
then usable until dawn.  Around 2 AM the temperature started to 
plummet and the humidity started to rise, and the seeing was 
mediocre at best after that.  But at least I got open, got some
data, and made sure everything worked OK.  It was never remotely
close to photometric.
