                 ------------- ACTIVITY LOG --------------
          1st & 2nd Half Observing Specialist: Jack Dembicky
 Turned on enclosure fans at 18:00.
 Lots of cirrus clouds at sunset which prevented opening on time.  Made
 for a very nice looking sunset but not much good for astronomy tonight.
 Clouds persisted thru the night with a sucker hole around midnight, that
 quicky vanished.  We then had another sucker hole appear around 04:00 but
 the satellite image showed more clouds on their way from the S and W. The
 2nd half observer had already called it quits earlier though due to the
 poor outlook from the IR satellite images.

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