                 ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 High dust before sunset kept us from cooling properly, but by the
 time the sun was down I felt comfortable enough to try opening with
 the fans in an odd configuration.  This was successful in keeping
 the dust counts low inside the dome, so we were able to work for
 several hours until the dust spiked up again after 01:30.  It didn't
 show any signs of dropping before morning.
 We had a little trouble with an apparent communications slowdown in
 the evening, but that cleared itself up and everything went smoothly
 from then on.

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