Institution(s): Columbia University

Instrument: 8K Camera

Worked for 2 hours (off and on through the night)
Conditions were Mixed most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   High Humidity all night.
   Beg: Clear, Winds Calm
   Mid: Clear, Winds Calm
   End: Seeing 1.6 arcsec, Clear, Winds Calm

Observing Summary:

We collected sky flat images at dusk for both I and R filters.
We had to close the mirror covers immediately after because of
high humidity, and monitored the weather conditions for the rest
of the night. The humidity started dropping rapidly at 4am (from
100% to under 30% within less than an hour!)and we started
immediate collection of object images. We had only enough time 
to obtain one image per field and filter before closing up 
the telescope and leaving for the airport on our way back home.
