MDM Observatory 2.4m Telescope Observing Report for 2016 Dec 07 Observer(s): Douglas, Núñez, Gibson Institution(s): Columbia University Instrument: Modspec/Nellie No Observing (see comments below) Conditions were Mixed most of the night. No equipment or software problems were encountered. Seeing and Weather: High Humidity all night. Observing Summary: Very high humidity dominated the whole night. During the first half it stayed at around 85-90%, and during the second half, around 95-100%. We therefore did not open the dome or window covers at all. The first half also had a significant amount of cirrus clouds, while the second half was mostly clear. ------------------------------ Submitted on 2016 Dec 8 [4:48:54]
