Comments: 

Fairly cloudy all night, estimated 2-4 magnitudes of extinction throughout.  When observation was possible seeing was about 1.0-1.4 arcsec.  Opened about 3 hours late due to wheather, opened up while there was a brief hole in the clouds, things improved slightly over time, but clouded over later in the night, so the telescope was closed.
