MDM Trouble Report for 2007 Apr 24 Telescope: 1.3m Observer(s): Bird and Watson (Ohio State University) Instrument: CCDS Problem(s) Encountered: We had a continuation of the Dome AZ encorder problem encountered last night, albeit to a lesser extent. Once the Dome AZ reading, and subsequently the dome error, jumped approxamately 30 degrees. The encoders read 333 while the actual value was ~296. The jump coincided with moving the dome slightly. On subsequent pointings, the optimal dome error varied from 0.0 to 9.0. This is quite an improvement over last night. We still checked the dome position almost every exposure to confirm the position, losing approx. 15 min over the night. ------------------------------ Submitted on 2007 Apr 24 [4:38:26]
