MDM Observatory 2.4m Telescope Observing Report for 2017 Apr 08

Observer(s): Edmund Hodges-Kluck
Institution(s): Michigan

Instrument: OSMOS R4K

Worked for 9 hours (all night)
Conditions were Non-Photometric most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Beg: Seeing 0.86 arcsec, Cirrus, Winds Light & Variable
   Mid: Seeing 0.9 arcsec, Cirrus, Winds Light & Variable
   End: Seeing 1.2 arcsec, Clear, Winds Calm

Observing Summary:

The weather was generally good, although there was high cirrus for
much of the night and the humidity rose to >70% around 3 am. I
observed 6 targets and shut down early in order to drive down the
mountain in the morning.

The dome entered its 'fugue state' at about 12:05 am, but following
the instructions on the website fixed the problem after about 10
minutes. 

I noticed tonight that the instrument rotator offset seems off by
about 1.5 degrees, but I can't tell if it's a constant offset or
if there is scatter (see trouble report).
