MDM Observatory 2.4m Telescope Observing Report for 2015 Apr 08

Observer(s): Stephan Frank
Institution(s): OSU

Instrument: OSMOS

Worked for 11 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 1.5 arcsec, Clear, Winds Light & Variable
   Mid: Seeing 1.5 arcsec, Clear, Winds Calm
   End: Seeing 1.5 arcsec, Patchy Clouds, Winds Light & Variable

Observing Summary:

When a few more very thin clouds moved in, the guider at times lost
its star in the 64x64 window-setting -- hence I changed the track box size
to the maximum 128x128.

In the end, I changed it back to the normal 64x64, to not change 
from I believe to be the default set-up.
