Observer(s): Rhiannon Griffin, Jenna Nugent
Institution(s): University of Oklahoma

Instrument: OSMOS

Worked for 2 hours (off and on through the night)
Conditions were Non-Photometric most of the night.
Problems were encountered, see the separate trouble report for details.

Seeing and Weather:
   Clouds from 8:00p until 11:00.
   Beg: Patchy Clouds, Winds Light & Variable
   Mid: Clear, Winds Calm
   End: Overcast, Winds Calm

Observing Summary:

We started the evening around 6pm with dome flats. When filling 
the dewar, part of the hose inflated. However, we were able to finish
filling it. Since we are waiting on a tube replacement, we did not 
refill the dewar at the end of the night.

The dome flats had dark, circular splotches in the center, indicating
there may have been water on the primary mirror or perhaps the 
dewar window. When the threat of rain occurred, we sent the
telescope home and closed the mirror covers.

Around 11:00pm we opened up again, when the sky had become relatively 
clear. The dark, circular effects were gone from the images. Upon 
noticing the tilt meters were off (x=+0.02, y=+0.02),
we went through the pointing procedure. We had difficulty regaining 
pointing, due to several reasons: user error, guide star selector
orientation off, tilt meter zenith value off, cloud and moon 
interference. When cloud cover became overcast, at 4:00a
we shut down for the night.
