                ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 Variable high clouds, too thick to shoot through about half the
 time.  Moderate to poor seeing.  No problems.  Focus behavior was a
 little weird, which sometimes happens in the spring.  Dust went over
 the limit during morning twilight, but I pushed it a little since
 counts in the dome stayed low.

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