MDM Trouble Report for 2002 Oct 23 Telescope: 1.3m Observer(s): A. Stutz (OSU) Instrument: 8K Problem(s) Encountered: After taking some bias frames I noticed that the dewar was not at the right presure, so I refilled it. After that it returned tto the normal presure (.3mT) Then clouds rolled in, and I had to stop. Humidity was high. While it was cloudy, Jen ran some tests on dome flats. While one of the exposures was reading out there was a software error: High voltage not enabled at utility board for 1st 2nd Then, after spewing out this error a few times, the problem seemed to go away, ie, the software gave no more errors. However, every exposure after this was over-exposed. A 30 sec R_tj M31 image had a mean of 25000, instead on a mean around 4000. Not knowing what was going on, I stoped observing. ------------------------------ Submitted on 2002 Oct 24 [0:25:56]
