                  ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 High winds and dust again kept us closed at the start of the night.
 When the dust dropped, we opened to clear skies and terrible seeing,
 which unfortunately did not improve as the telescope equilibrated.
 Switching to the IR for second half did help the seeing somewhat, but
 compared to GRIM's usual standard it was still rather poor.
 Everything worked smoothly -- not so much as a peep from the GRIM Mac.

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