                 ------------- ACTIVITY LOG --------------
 Observing Specialist: Russet McMillan
 The engineering work was completed this afternoon, and the telescope
 checked out in time to cool before sunset.  After the observer took
 some twilight flats, I did a quick check of pointing and collimation
 and found both to be adequate though not perfect.  We went on to
 science.
 The entire night was clear and apparently photometric, with seeing
 ranging from 0.8 to 1.5 arcsec.  We closed for a couple of hours due
 to high winds with gusts over 40 mph, but otherwise everything went
 smoothly.

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