MDM Observatory 2.4m Telescope Observing Report for 2019 Jun 13

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

Instrument: OSMOS/B

Worked for 9.5 hours (all night)
Conditions were Non-Photometric most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Clouds all night.
   Beg: Seeing 1.4 arcsec, Patchy Clouds, Winds Calm
   Mid: Seeing 1.3 arcsec, Patchy Clouds, Winds Calm
   End: Patchy Clouds, Winds Light & Variable

Observing Summary:

Patchy clouds hindered observations until about 11, at
which point it cleared up for a little bit. More clouds
rolled in at around 1:15, a stuck around until twilight.
No technical issues, although in a couple frames there
seemed to be some sort of obstruction in the optical path.
It certainly wasn't the guide probe, and it didn't seem
to stick around. Fortunately in those couple frames where
it did appear, it stayed on the edges.
