                ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: R.McMillan
 High winds in the afternoon kept us closed until a little after
 sunset, but they dropped below the limit by the time it was dark
 enough to focus.  Thin high clouds persisted throughout first half,
 with very good seeing at the beginning of the evening turning to
 moderate seeing a little later.  NIC-FPS again needed to be reset
 during afternoon checkout, but fortunately it recovered after only
 one reset, since I wasn't up to multiple trips up the stairs.
 2nd Half Observing Specialist: B.Ketzeback
 Second half went smoothly. Cloud cover was same as first half. No problems.

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