                  ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan, W.Ketzeback
 High humidity and thick clouds kept us closed throughout the first
 half.  After 02:00, the humidity began to drop, but it took a
 while for the clouds to thin out.  We finally opened at 03:45 and had
 enough time to focus and get a couple of science exposures (on a
 third-magnitude star!) before the clouds returned.  Another opening
 presented itself shortly before twilight, and we took advantage of
 that until the sky was too bright for science.  Despite the poor
 seeing conditions and limited time, the observer said he was able to
 finish two science targets.

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