MDM Observatory 2.4m Telescope Observer's Report for 2006 Nov 27

Observer(s): Eastman
Institution(s): OSU

Instrument: CCDS

Worked for 5 hours (off and on through the night)
Conditions were Mixed most of the night.
Problems were encountered, see the separate trouble report for details.

Seeing and Weather:
   Very bad weather from 6 until 12.
   Beg: Seeing 0.9 arcsec, Patchy Clouds, Winds Calm, High Humidity
   Mid: Seeing 1.25 arcsec, Clear, Winds Calm
   End: Seeing 1.0 arcsec, Clear, Winds Calm

Observing Summary:

The night started off with dark clouds overhead. When they cleared,
I opened up, and promptly had to close because the humidity 
jumped to 92% (from 75%). The humidity stayed above 95% for a few
hours, then dropped back down just as suddenly. After waiting a 
while to make sure it wouldn't jump right back up, I opened again
and observed the rest of the night.

There was one point that I think the cold weather affected the 
guiding. See the trouble report for more details.
