                ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 The night started out with thin cirrus, thickening to heavier stuff
 mid-evening.  The first half observer gave up an hour or so early,
 and the second half observer got a sucker hole barely just long
 enough to focus through.  I managed to catch a ToO during morning
 twilight because it was bright, but the S:N wasn't very good.
 NIC-FPS was on the pump and unavailable tonight; the DIS ion pump
 also continued to show increasing pressure levels, and the observer
 mentioned signs of a return of the scattered light on the blue side.

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