                  ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: W.Ketzeback
 Clouds, high winds and high humidity prevented openning first half of the
 night. Light snow flurries set off the rain sensor around 2100.
 2nd Half Observing Specialist: R.McMillan
 The snow had pretty much stopped before midnight, but heavy clouds
 and high winds and very powdery snow on the ground made opening
 impossibly.  I didn't run the snow program, but did change the
 telescope's profile to the wind for a while.

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