MDM Observatory 2.4m Telescope Observing Report for 2012 Jan 25

Observer(s): Shields and McGraw
Institution(s): Ohio University

Instrument: OSMOS/Blue

Worked for 12 hours (all night)
Conditions were Non-Photometric most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Beg: Seeing 2.2 arcsec, Cirrus, Winds Light & Variable
   Mid: Seeing 3.5 arcsec, Clear, Winds Light & Variable
   End: Seeing 2.2 arcsec, Clear, Winds Light & Variable

Observing Summary:

Seeing was pretty bad most of the night, thin cirrus clouds early but sky 
was very clear for most of the night.  Some inefficiencies in the first
half of the night due to changes in instrument setup from its state
during our previous run.  Bias showed some anomalies in early
exposures during the afternoon, not seen later.  Consultation with
Paul Martini suggests this is temporary flakiness associated with
getting the detector cooled back down and running again.
