MDM Observatory 1.3m Telescope Observing Report for 2012 Feb 04

Observer(s): Mogren
Institution(s): Ohio State

Instrument: CCDS

Worked for 10 hours (all night)
Conditions were Non-Photometric most of the night.
Problems were encountered, see the separate trouble report for details.

Seeing and Weather:
   Beg: Seeing 2.1 arcsec, Cirrus, Winds Calm
   Mid: Seeing 1.2 arcsec, Clear, Winds Calm

Observing Summary:

Cirrus clouds were present at the beginning of the night, but the sky
cleared up later on and seeing improved.  I noticed the telescope had
a tendency to drift westward.  I had to realign the object with the
slit after one or two 20 minute exposures.
