                 ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 Clouds, precipitation that perpetually approached but never arrived,
 and a strong dust spike kept us closed during first half.  By the
 time the dust dropped, most of the clouds were disappearing as
 well.  We still had a telescope well out of equilibrium due to the
 lack of cooling during the dust storm, but it was easy enough to
 follow the focus up from -250 to 0 over the course of two and a half
 hours.  Everything worked perfectly.

     Note: the wind was coming from the azimuth listed.  The convention
     used is north=0 degrees, east=90 degrees.  The dust count is
     particles > 1u per 0.1 cubic feet.
