                  ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 Clouds and high humidity started the night.  The humidity started to
 break around 22:15 and the clouds appeared to be moving out, but the wind
 direction was also changing to the NE (where the clouds were moving) and
 the humidity was still around 75% so I decided to wait to make sure
 things were good before opening.  By 22:45 I informed my observer that we
 would probably be ready to open shortly and he could start taking some
 wavecals with DIS.
 I just about finished focusing DIS when the clouds moved back in from the
 West.  It remainded cloudy the remainder of the night.

     used is north=0 degrees, east=90 degrees.  The dust count is
     particles > 1u per 0.1 cubic feet.
