MDM Trouble Report for 2011 Jan 20

Telescope: 1.3m
Observer(s): Jackie Faherty and Sebastien Lepine (American Museum of Natural History)
Instrument: MKIII

Problem(s) Encountered:
We filled the dewar before sunset at ~5:30pm.  Observing was fine until 
~4am when the detector counts started to rise.  I was troubleshooting the problem (not realizing that the
detector temperature was the problem) for ~1 hour before Sebastien
came down from the 2.4m and noticed that the problem must be a hot detector.
We immediately filled the dewar but the temperature of the detector had
risen significantly.
