                ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 First we spent a few hours waiting for the thunderstorm.  Then we
 spent a few hours watching and listening to the thunderstorm.  Then
 we spent a few hours watching clouds.  Then, at last, the Sloan
 observers decided to give up, and conditions improved at once.  We
 were able to get on the sky for about an hour and do some useful
 comparisons of the new echelle slitviewer vs. the dis slitviewer.
 They are comparable in sensitivity, allowing for the difference in
 pixel scales.

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