MDM Observatory 2.4m Telescope Observing Report for 2010 Dec 15

Observer(s): S. Lepine
Institution(s): AMNH

Instrument: Direct + Echelle

Worked for 13 hours (all night)
Conditions were Non-Photometric most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Beg: Seeing 1.0 arcsec, Cirrus, Winds Light & Variable
   Mid: Seeing 0.9 arcsec, Cirrus, Winds Light & Variable
   End: Seeing 1.0 arcsec, Clear, Winds Light & Variable

Observing Summary:

The night was unexpectedly clear.  The weather forecast
called for significant cloud cover, but the (rather large) 
system grazed us to the north, only sending a few bands of 
thin cirrus clouds, and the worst was avoided. Observed all 
night, covering 23 targets from the parallax program.
