MDM Observatory 2.4m Telescope Observing Report for 2017 Jan 04

Observer(s): Simonian
Institution(s): OSU

Instrument: OSMOSB4k

Worked for 13 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 1.3 arcsec, Cirrus, Winds Moderate
   Mid: Seeing 1.3 arcsec, Cirrus, Winds Moderate
   End: Seeing 1.3 arcsec, Cirrus, Winds Moderate, Twilight clouds

Observing Summary:

Clear all night with cirrus clouds passing overhead. Winds were 
consistently about 20 mph. However, general imaging projects were 
easy to follow-through with. Around 4pm, guiding stars became 
particularly difficult to find despite there being no apparent 
clouds. Around the same time, guide stars appeared to drift out 
of the telescope field of view. However, I was able to make it 
through the whole night, albeit with less efficiency toward the 
end.
