MDM Trouble Report for 2016 Jun 20 Telescope: 2.4m Observer(s): Weil (Dartmouth) Instrument: Modspec + Echelle CCD Problem(s) Encountered: Telescope would not record data from the slit and only recorded zeros, not even a bias level. Called Eric Galayda at beginning of night to try to find a solution. he tried restarting the computer, restarting the electronics on the telescopes and none of these seemed to help. The electronics box was then shut down for an hour to let it cool down, but at this point KPNO had closed the 4m due to smoke so the dome and telescope remained off for the rest of the night. ------------------------------ Submitted on 2016 Jun 21 [1:59:14]
