MDM Observatory 2.4m Telescope Observing Report for 2009 Feb 17

Observer(s): John Thorstensen

Instrument: echelle CCD + buckeye FW

Worked for 3 hours (last half of the night)
Conditions were Mixed most of the night.
No equipment or software problems were encountered.

   Clouds from start until 3 AM.
   Beg: Overcast, Winds Light & Variable
   Mid: Fog/Low Clouds, Winds Light & Variable
   End: Seeing 1.5 arcsec, Clear, Winds Light & Variable

Observing Summary:


Low clouds were predicted to clear, but took their own sweet
time doing so -- and then the humidity was too high for a while.
The humidity finally dropped around 3 AM, as the last of the 
clouds went away.  The seeing was OK to mediocre after that.
