MDM Observatory 1.3m Telescope Observing Report for 2014 Feb 07

Observer(s): Coker
Institution(s): Ohio State

Instrument: CCDS

Worked for 11 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 1.4 arcsec, Patchy Clouds, Winds Light & Variable
   Mid: Seeing 1.7 arcsec, Cirrus, Winds Light & Variable
   End: Seeing 1.3 arcsec, Cirrus, Winds Light & Variable

Observing Summary:

The night started with patches of clouds at sunset which quickly 
dissipated, leaving only some light cirrus in their wake.  Hazy 
but essentially clear conditions prevailed for the rest of the
night; the haze/cirrus grew thicker as the night went on.  I
was able to observe all planned targets except as noted below.

While attempting to observe Akn 120 and NGC 2617, the telescope
began  nodding  north-south with amplitudes of 0.5-1' or more.
This totally precluded observing Akn 120, but did not occur until
my third exposure of NGC 2617, so I was able to get some good 
data from that.  Both targets were close to the meridian at the
time of the problems, and both are near the celestial equator.
The nodding did not affect observations in any other part of 
the sky.
