                  ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 Rain threats disappeared by sunset, but humidity was a problem.  I
 decided to open for just a bit and take advantage of the warm
 telescope.  This wasn't enough time to make much of a dent in the
 scheduled UW program, but we caught a quick nova for the CorMASS
 scientists until I discovered that the telescope temperature sensors
 were stuck and we were closer to the dewpoint than I suspected.
 After a couple of hours, the dewpoint dropped again and we pursued
 Galactic bulge targets into the treeline.  The updated NA2 guider
 software behaved beautifully on crowded fields with horrible seeing
 at airmasses up to 6.5!
 Second half went very smoothly with the echelle except for a crash
 of the slitviewer ICC which required a little coddling to recover.

     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.
