                 ------------- ACTIVITY LOG --------------
 Observing Specialist, 1st Shift: Noel Camron Hastings
     Opened the dome at 16:50 MST to allow for cooling. Partly cloudy
skies. No troubles encountered in startup and first half ran smoothly.
Clouds grew thick as the night went on and we closed at 23:42.
 Observing Specialist, 2nd Shift: Russet McMillan
Second half started with thick clouds and some precipitation showing
nearby on radar, but we were able to open after about 03:00 when the
clouds cleared off.  Seeing was quite variable, jumping from about 1.0
to 1.5 arcseconds on short timescales.  The observers had trouble at
first getting the slitviewer control program to run at their end, so I
ran it for a little while.  Eventually they got the problem
straightened out, and everything else went quite smoothly.

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