MDM Observatory 2.4m Telescope Observing Report for 2009 Feb 03

Observer(s): R. Mark Wagner
Institution(s): Ohio State University/LBT

Instrument: CCDS

Worked for 7 hours (part of the night)
Conditions were Mixed most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Clouds from 00:00 until 04:00.
   Beg: Seeing 2-3 arcsec, Clear, Winds Light & Variable
   Mid: Seeing 2-3 arcsec, Cirrus, Winds Light & Variable
   End: Clear, Winds Calm

Observing Summary:

Night started out very well.  Photometric.  Seeing was worse than last night and quite
variable.  The IR satellite showed a small group of clouds passing through southern
Arizona.  These started to affect observations on and off around midnight.  Needing
photometric skies for the CCDS throughput verification I quit around 2:30 am.  There
were still patchy clouds at 4:00 am.   No instrument or telescope problems.  When
was the last 2.4 m pointing model?  Tracking a star while waiting for it to clear showed
some definite pointing variations that I would expect to be taken care of by an 
accurate pointing model.
