                ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: J. Dembicky
 No problems.
 2nd Half Observing Specialist: R.McMillan
 Second half was fairly peaceful, with some niggling problems: poor
 tracking in azimuth that I couldn't ascribe to wind, a readout
 failure on one spicam image which recovered by itself afterward, a
 guiding failure when offsets collided, fascinating new (low-level)
 noise patterns on DIS.  Nothing that cost significant time, just
 enough to keep me awake.

     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.
