Worked for 9 hours (all night)
Conditions were Non-Photometric most of the night.

   High Humidity all night.
   Beg: Seeing 1.5 arcsec, Patchy Clouds, Winds Calm
   Mid: Seeing 2.0 arcsec, Clear, Winds Calm
   End: Seeing 1.8 arcsec, Clear, Winds Calm

Observing Summary:

At the beginning of the night, we discovered water had condensed on to the CCD window, and so we had to blow it off with dry Nitrogen.

We attempted to take spectra of several CV candidates, but many were too faint to observe; two good candidates were observed.

Seeing was at best 1.5 , which was not sufficient for some imaging attempted at the end of the night.

We re-focused once during the night.
