Observer(s): Santana
Institution(s): Ohio University

Instrument: R4K

Worked for 12 hours (all night)
Conditions were Non-Photometric most of the night.
Problems were encountered, see the separate trouble report for details.

Seeing and Weather:
   Beg: Cirrus, Winds Light & Variable
   Mid: Seeing 1.01 arcsec, Cirrus, Winds Light & Variable
   End: Seeing 1.6 arcsec, Cirrus, Winds Light & Variable

Observing Summary:

Moisture was dried off the window just after sunset.  Spent 
first part of night getting calibrations and set up.  About
midnight started science frames, the seeing varied due to 
cirrus clouds, from about 0.9 to 1.6.  At one point in the 
night images were not showing up in the data folder.  I 
closed Prospero thinking it was not writing them.  Once 
restarted the files that were missing showed up all at once,
unsure of the quality I retook those specific images (short 
10 second standard and 1 second focus shots).  At another
point, prospero appeared to hang on an exposure, quitting
the exposure and re-initializing it worked.
