                ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 Clouds and dust first half, clouds and humidity second half.  Often
 the conditions were just barely borderline, but they didn't
 stabilize enough to be safe until after midnight.  Even once the
 dome was open, less than half the time was useful because of clouds.

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