                  ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: J.Barentine
 Clearer skies this afternoon than 24 hours previously, but the high winds
during the day meant correspondingly high dust counts.  The dust kept us
closed until after 20:00, when diminishing winds brought the dust levels
down with them.  Clouds rolled in later toward the end of first half;
otherwise, all was quiet.
 2nd Half Observing Specialist: W.Ketzeback
 Clouds cleared for 2 hours from about 0130 to 0230 and then got gradually
 thicker until we closed early at 0515 due to opaque conditions.

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