                ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: J.Barentine
 NIC-FPS functioned well in first half, and the weather cooperated.  Nice
night.
 2nd Half Observing Specialist: R.McMillan
 Second half started with clear skies and moderate seeing.  We had
 some intermittent troubles with the DIS slitviewer shutter, but it
 always recovered after one or two images so it cost very little time.

     Note: the wind was coming from the azimuth listed.  The convention
     used is north=0 degrees, east=90 degrees.  The dust count is
     particles > 1u per 0.1 cubic feet.
     Note: The Tower Dust counter appears to be down at this time
