                   ------------- ACTIVITY LOG --------------
  1st Half Observing Specialist: J.Barentine
  Thick clouds, precip in the region on radar.
  2nd Half Observing Specialist: R.McMillan
  A gap in the clouds arrived shortly after 01:30 and we were able to
  make good use of it.  Several hours of the morning were clear and
  apparently photometric, although seeing was poor.  More clouds
  started moving in right at morning twilight.

    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.
