                   ------------- ACTIVITY LOG --------------
  1st Half Observing Specialist: J.Barentine
  Opened just after 18:45.  Skies were full of moderately thick cirrus
which dissipated toward 21:00.  Altogether quiet first half.
  2nd Half Observing Specialist: R.McMillan
 Second half was mostly clear but with a few waves of thin cirrus.
 Seeing started out very good, then deteriorated to moderate; later
 observations were all made at high airmass and therefore hard to
 judge.  Everything went very smoothly.

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