                ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 We opened during twilight with widespread thin clouds and borderline
 humidity.  The humidity remained just below the limit for some hours
 and the observers were able to get a little data through the clouds
 with the help of good to excellent seeing.  Around 23:00 the
 humidity went over the limit, and we closed for the remainder of the
 night.

    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.
