                ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 All four of our regular facility instruments were used tonight, and
 all behaved nicely.  So did the telescope.  For much of the night we
 had mostly clear skies with occasional high clouds, and moderate to
 poor seeing.  The first half transient program was split between a
 little bit of GRB followup and payback for a program that lost time
 to the last GRB followup.  After 03:00 more extensive clouds began
 to move in and thicken.  The second half observer was unable to get
 any data after about 05:00, so he handed over to UW13 early.

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