                ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 A beautifully clear night with decent seeing first half, bad seeing
 second half, and another smattering of minor problems.  The dcam nub
 got locked up once during first half and needed to be restarted,
 taking only a minute.  Then during second half the DIS slitviewer
 suddenly started returning images that were all zeroes.  I was
 unable to get it reinitialized, but found that we could still get
 normal images with the old slitview program, so I had the observer
 change over and lost only a little time.  Everything else worked
 normally.

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