MDM Observatory 2.4m Telescope Observing Report for 2016 Dec 06 Observer(s): Douglas, Núñez, Gibson Institution(s): Columbia University Instrument: Modspec/Nellie Worked for 0.5 hours (first half of the night) Conditions were Overcast most of the night. No equipment or software problems were encountered. Seeing and Weather: Beg: Cirrus, Winds Light & Variable Mid: Cirrus, Winds Light & Variable End: Cirrus, Winds Light & Variable Observing Summary: The night started with humidity near 70% and some patchy cirrus clouds, so we observed some targets for 30 minutes. Humidity increased quickly, however, and we closed the telescope and dome when it reached 80%. Humidity remained above at least 85% for most of the night and cirrus clouds took over the sky. Three hours before twilight started, humidity came back down to the mid 70s%, but the sky remained covered with high cirrus clouds. ------------------------------ Submitted on 2016 Dec 7 [4:17:23]
