MDM Observatory 2.4m Telescope Observing Report for 2011 Jan 19

Observer(s): Jackie Faherty and Sebastien Lepine
Institution(s): American Museum of Natural History

Instrument: Nellie

Worked for 10 hours (all night)
Conditions were Non-Photometric most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   High Humidity from 2 until 7.
   Beg: Seeing 1 arcsec, Clear, Winds Moderate
   Mid: Seeing 1.5 arcsec, Clear, Winds Light & Variable
   End: Seeing 1 arcsec, Clear, Winds Calm

Observing Summary:

The night started with 10-12 mph winds.  In the middle of the night 
the humidity crept up to 75%.  Condensation appeared on the images as 
a result.  At the end of the night we turned the lamp lights on to attempt 
to clear the condensation.  

While observing a star close to the zenith the dome seemed to get stuck and 
kept moving back and forth.  I moved to a different target and the problem was resolved.
