MDM Observatory 2.4m Telescope Observing Report for 2016 Aug 05 Observer(s): Yiseul Jeon, Donghoon Son Institution(s): Seoul National University Instrument: OSMOS/B No Observing (see comments below) Conditions were Mixed most of the night. Problems were encountered, see the separate trouble report for details. Seeing and Weather: Clouds from 8 until 10. Observing Summary: After KPNO opened their domes around 10PM, the 2.4m also started to do our observation. However when I was doing the start-up procedure, the mirror covers (all of 4) failed to open. We could not solve this problem. The details are described in the trouble report. ------------------------------ Submitted on 2016 Aug 6 [4:44:32]
