                ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: J.Barentine
 Quiet first half with good seeing, virtually subarcsecond, throughout.
The NA2 guider was well-behaved with none of the errors seen in recent
nights.
 2nd Half Observing Specialist: R.McMillan
 Mostly photometric skies and subarcsecond seeing continued through
 second half.  Everything worked perfectly, including the guider
 shutter.

     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
