Observing Summary:

Cloudy for the first half of the night. Clearing around midnight.
Opened at 12:30 to clear skies, good seeing.  By the end of the
night, however, there was cirrus everywhere and the seeing was
not as good.  The lightest LN2 dewar is now empty. I started 
using the second lightest one. I am turning the CCD electronics
off during the day to keep it from overheating.
