                  ------------- ACTIVITY LOG --------------
 First Half Observing Specialist: Russet McMillan
 The PI for the scheduled UW programs was stranded in a distant locale
 by airport closures, so a couple of other UW observers took over the
 night.  Institutional codes will be worked out later.
 The weather started out quite lovely -- dry, clear and apparently
 photometric, with good seeing. The telescope was opened shortly
 before sunset for cooling, and seeing was subarcsecond by the time it
 was dark enough to focus.  Seeing remained good for most of first
 half, but deteriorated somewhat after midnight.
 The telescope and instruments worked well aside from a few bobbles
 resolved during checkout and a non-photometric background on the
 guider which didn't impede guiding capabilities.
 Second Half Observing Specialist: Noel Camron Hastings
 Things were running smoothly when I arrived and stayed that way!

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