MDM Observatory 2.4m Telescope Observing Report for 2019 Nov 23 Observer(s): Nunez Institution(s): Columbia Univeristy Instrument: OSMOS/B Worked for 8 hours (most of the night) Conditions were Non-Photometric most of the night. Problems were encountered, see the separate trouble report for details. Seeing and Weather: Beg: Cirrus, Winds Light & Variable Mid: Cirrus, Winds Light & Variable End: Cirrus, Winds Calm Observing Summary: Cirrus clouds dominated the night. Humidity remained near 60% all night. I had to pause observing a couple of times during the night, when even bright objects were hard to get through the clouds. The hose on one of the nitrogen tanks is leaking a bit. I still could fill up the dewar without a problem, though. ------------------------------ Submitted on 2019 Nov 24 [4:19:12]
