MDM Observatory 2.4m Telescope Observing Report for 2019 Sep 14

Observer(s): Rupert
Institution(s): MDM

Instrument: OSMOS/B

Worked for 3.5 hours (off and on through the night)
Conditions were Mixed most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Clouds from start until 12:00.
   Beg: Seeing 2.7 arcsec, Patchy Clouds, Winds Light & Variable
   Mid: Seeing 2.1 arcsec, Patchy Clouds, Winds Calm
   End: Clear, Winds Calm, High Humidity

Observing Summary:

Opened with patchy clouds and a humidity that was slowly
increasing. Ended up closing at 7:45 after the humidity
hit the observing limit. Overcast conditions ensued shortly
after. 

At around 10:30 I opened again with the humidity down
and the clouds at least partly cleared. Didn't take long for
some to come back, making observations difficult. Actually
started taking data at 11:45.

The humidity creeped up again, finally exceeding the limit
at 1:45. I remained closed for the rest of the night.

*sigh*
