MDM Trouble Report for 2013 May 24

Telescope: 2.4m
Observer(s): Katie Wolf and Claire Ding (Columbia)
Instrument: Templeton

Problem(s) Encountered:
The Owl log kept showing warnings about being unable to calculate the average temperature. We weren't sure what was wrong so we started observing. We got a few good images before Owl stopped responding. The log kept showing an error that read something like  Reset controller failed . First we tried going into Setup and reapplying the controller settings, but that didn't work. Next, we exited Owl and restarted it, but it also didn't register a change. We called Eric and he guided us through shutting down the CCD controller and restarting it and Owl. At first, Owl appeared to be working again, and then the same warnings about temperature showed up, followed by the same error about the reset controller fail and Owl stopped responding again. We shut down the controller again and restarted Owl and this time it worked.
Also, we noticed that Owl read out a controller temperature of -7.6 C when we had just filled the dewar. This happened on multiple occasions.
