MDM Observatory 2.4m Telescope Observing Report for 2013 Sep 30

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

Instrument: CCDS

Worked for 12 hours (all night)
Conditions were Photometric most of the night.
Problems were encountered, see the separate trouble report for details.

Seeing and Weather:
   Beg: Seeing 1.5 arcsec, Clear, Winds Light & Variable
   Mid: Seeing 1.2 arcsec, Clear, Winds Light & Variable
   End: Seeing 1.2 arcsec, Clear, Winds Light & Variable

Observing Summary:

Sky was clear all night, good observing conditions.  At 4:20 am, the guider stopped moving in both the x and y directions.  I recycled the power and restarted xmis, and this fixed the problem.
Also I noticed there is a leak at the end of the liquid nitrogen hose where the zipties are clamped on.  As I went out to fill the dewar at 5:30 am, the dewar temperature had warmed to -82 degrees.
I am not certain as to whether this was due to it not being filled properly or something with the dewar itself.
