                  ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: J.Barentine
 Moderately-thick cirrus overhead at sunset.  NA2 Guider crashed almost as
soon as we started during a focus loop, but that was the only trouble
encountered during first half.  Initially poor seeing improved through the
duration of the half.
 2nd Half Observing Specialist: R.McMillan
 Second half was clear with variable seeing.  Everything worked well
 aside from the still-unhappy tertiary rotation clamp, which needed
 to be cajoled into closing via low-level commands.

   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 weather tower dust counter is out of commision
