                   ------------- ACTIVITY LOG --------------
 1st half Observing Specialist: B.Ketzeback
 Clear skies, everything worked fine.
 2nd half Observing Specialist: R.McMillan
 Second half also went smoothly, aside from having to chase focus up
 and down after 02:00, when the seeing was subarcsecond and we were
 more sensitive to focus change.  There were two slitviewer ICC
 crashes, but both occurred in the middle of exposures and lost us no
 time.
 After the program changeover, while the second half person was
 taking some cals, I made use of the time to get a Shack-Hartmann
 measurement.  The spherical aberration is still a little higher than
 usual, but not grossly elevated.  I still think something more is
 going on than just thermal disequilibrium.

     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.
