                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 Excellent seeing tonight, sub arc sec all night.  I tweaked it on the fly
 for the first half (both instrument and guider). The shutter on the
 slitview camera still was acting flakey but I don't know if it was better
 than last night or not.  My observers didn't complain to much but I also
 told them just to take images and then next image would usually clear the
 problem.  It also wasn't as cold tonight as last night.
 Humidity shut us down in the 2nd half around 03:40.  We never re-opened.
 A very productive night sciencewise.

     Note: the wind was coming from the azimuth listed.  The convention
     used is north=0 degrees, east=90 degrees.  The dust count is
     particles > 1u per 0.1 cubic feet.
