                  ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 High humidity and clouds kept us closed first half. At around midnight the
 skies cleared and the dewpoint differential slowly grew enough that we were
 able to open at 0100. There was just enough time for focusing and completion
 of the instrument block before the wind shifted from east to south and the
 humidity again spiked closing us down for the remainder of the night.

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