                ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 High dust, nearby precipitation, and fast-moving clouds kept us
 closed for the first few hours.  Once the precip was past and the
 dust was down, I opened to let the observer wrestle with the clouds.
 Then the clouds got thicker and it looked like an orographic
 formation.  I had just told the observer we would be closing when
 the rain sensor went off.  The telescope got a smattering of drops
 on it, mostly on the NA1 side, and would like to be cleaned if
 possible during the day.
 The clouds and radar traces didn't resolve in time to be of use to
 the second-half observer.

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