MDM Observatory 1.3m Telescope Observing Report for 2014 Jan 04

Observer(s): Michael Fausnaugh
Institution(s): OSU

Instrument: CCDS

Worked for 8 hours (all night)
Conditions were Mixed most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Clouds from 00 until 08.
   Beg: Overcast, Winds Calm
   Mid: Seeing 1 arcsec, Patchy Clouds, Winds Calm
   End: Seeing 1 arcsec, Cirrus, Winds Calm

Observing Summary:

Weather started overcast, progressively lightened over the night.

Delayed opening by 3 hours.  Closed mirror cover at 06 UT because
unable to acquire sufficient signal to noise.
Reopened at 07:30 UT, and by 08:00 UT, conditions had lightened to
hazy/cirrus clouds.

Observed 5 usable AGN, 3 standard stars.

No major technical difficulties.  Did have some N-S nodding, at
the normal 1 arcsecond amplitude.  These seemed to start after
I began sending dx/dy offsets to the guider for slit acquisition.
For most of the night, the nodding seemed correlated with using
the dx/dy offsets, but not 100%.
