MDM Trouble Report for 2016 Jun 27 Telescope: 2.4m Observer(s): Black, Neustadt, Schaible (Dartmouth) Instrument: OSMOS Problem(s) Encountered: the dome lost its positioning and tracking. The positioning issue may be due to observer error in accidentally reseting the dome encoders We stowed telescope, turned off auto dome and tracking, and manually moved the dome to home position. Then reset the dome encoders and started everything back up. This solved the position issue, but not the tracking. Dome would not adjust position during long exposures. We continued to move it manually so that we could take data while trying to troubleshoot. This didn't last very long as bad weather moved in before we had the chance to find a solution. ------------------------------ Submitted on 2016 Jun 28 [5:24:18]
