MDM Trouble Report for 2007 Nov 19 Telescope: 2.4m Observer(s): Assef & Atlee (OSU) Instrument: Direct/Echelle Problem(s) Encountered: The TCS failed to track when first starting up. This was resolved relatively quickly (with Bob's help) by restarting the TCS system and re-initializing. Had only a minor impact on observing efficiency, and did not recurr during the night. There appears to be a set of hot pixels in the CCD that saturate in a streak. We first noticed these early in the night, and they persisted throughout the night. They do not appear to have affected the region of interest in any images, and we think the data will all be useable. This is an outstanding issue. ------------------------------ Submitted on 2007 Nov 20 [7:05:24]
