MDM Observatory 1.3m Telescope Observing Report for 2012 Jan 22

Observer(s): Stoll and Roettenbacher
Institution(s): OSU and Michigan

Instrument: CCDS

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

Seeing and Weather:
   Clouds from UT 01 until UT 06.
   Beg: Seeing 1.3 arcsec, Patchy Clouds, Winds Light & Variable
   Mid: Seeing 1.4 arcsec, Clear, Winds Light & Variable
   End: Seeing 1.2 arcsec, Clear, Winds Light & Variable

Observing Summary:

Patchy clouds at sunset.  Gradually cleared over the next five 
hours.  Everything went smoothly.

I assume the periodic loud humming/squealing of one of the 
bits of (climate control?) machinery immediately outside the 
building around the corner to the left of the entrance to the 
control room is a known issue?  It happens on the order of 
once every hour or so.
