                  ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: Russet McMillan
 First half started out with cirrus, patchy clouds, and 0.8" seeing at
 the very beginning of the night.  Then the wind picked up, the seeing
 degraded to 2" or worse, and the skies cleared.  Jeff Morgan logged
 in from UW to do scattered light tests using SPIcam, both with and
 without the special tertiary baffle.  We also did some work on
 improving the consistency of the altitude magnasensors.
 2nd Half Observing Specialist: Jack Dembicky
 Everything seemed to run smoothly for the 2nd half of the night.  Jeff
 managed to get over 130 images!

   used is north=0 degrees, east=90 degrees.  The dust count is particles
   > 1u per 0.1 cubic feet.
