                ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: R.McMillan
 Rain, lightning, hail, and high humidity.  I occupied myself by
 mining various logs in pursuit of three observer information
 requests and two instrument-health questions.  No partridge or pear
 tree, but plenty of fresh apples.
 2nd Half Observing Specialist: B.Ketzeback
 Humidity started to drop around 2:30. I opened the cloud camera and while
 I was waiting for it to finish initializing, I did a safety walk around and
 test slews. We opened at 03:00. The first significant laser returns from
 the moon were seen at 03:55 under poor seeing conditions and moderate to
 strong winds. Weaker than expected but repeatable measurements were made
 off the Apollo 15 and Apollo 11 retro-reflectors tonight. Tom hopes to peak
 the returns over the next few nights by tweaking various parts of the system.
 Congratulations to Tom Murphy and his collaborators on achieving this
 significant milestone.

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