                  ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: J.Barentine
 Scattered clouds filled the sky around sunset when we opened, and as the
sky got dark the humidity started to rise.  Bruce used the twilight time
to get flats with GFP.  The sky rapidly cleared after sunset; winds
increased in this time and the seeing was consequently fair.  Seeing took
another rollercoaster ride up to nearly 3 arcseconds before settling down
in the neighborhood of 1.5 arcseconds later in the half.  Humidity also
backed off later, keeping us from having to close.
 2nd Half Observing Specialist: R.McMillan
 Second half went smoothly, with mostly clear skies.  Seeing started
 out poor and slowly improved to moderate (2.5-1.5 arcsec).  The only
 problem was a crash of the guider ICC, which didn't cost any time.

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