MDM Observatory 2.4m Telescope Observing Report for 2018 Feb 08

Observer(s): Douglas, Weaver, Carmichael
Institution(s): Columbia

Instrument: OSMOS/R

Worked for 8.5 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: Clear, Winds Light & Variable
   Mid: Clear, Winds Light & Variable, Smoke
   End: Clear, Winds Light & Variable, Smoke

Observing Summary:

The night started off clear, and despite our continued issues with
the guider we were able to get fairly good data by being more 
careful about keeping the guide probe further from the detector 
FOV. At around UT~10 the ARO observer alerted us to smoke outside,
and we closed down. Initially the 4m OA asked us to stay 
and monitor since we couldn't see fire anywhere; eventually the 
smoke level increased to the point it was coming into the 2.4m 
building and we went to the summit. The 4m OA had called 911 and
determined it was a known fire somewhere that was already being
worked on. We came back to MDM at sunrise and the smoke level 
has decreased enough we can sleep in the building but it's still
present outside.
