MDM Trouble Report for 2002 Jun 6 Telescope: 2.4m Observer(s): Monique Aller (University of Michigan) Instrument: MODSPEC + Wilbur Problem(s) Encountered: When using the instrument rotator, the rotator angle suddenly lept from something like 5 degrees to something like -663 degrees. I put the rotator in reverse and it seemed to go back to 5 degrees and I did not have a repeat of this problem during the night. Another, related, problem is that the monitor in the dome which displays the TCS information seems to have serious problems. It is so illegible that it is nearly impossible to read the rotator angle from the dome. I tried changing the brightness and horizontal/vertical holds but was unable to make the monitor even moderately legible. ------------------------------ Submitted on 2002 Jun 7 [4:43:27]
