                 ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 First half went very smoothly, with clear skies and mostly
 subarcsecond seeing.  Everything worked well.  Second half, the DIS
 ICC spontaneously rebooted while we were concentrating on focusing
 and acquiring the first target, so it first took a while to find the
 problem and then even longer to correct the ungraceful bits of
 connections lying around everywhere.  Once that was resolved and we
 got going, things settled down nicely.

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