                 ------------- ACTIVITY LOG --------------
                  Observing Specialist: Camron Hastings
   I opened at 17:30 MDT to begin cooling. Dust levels and wind were
acceptable, but temps were low. I took z' flats for the observers to help
speed things up. Offset and rotated between each to help average out any
scattered light we were getting. The seeing was variable and the temps
were  low and things ran smoothly all night. The Princeton team managed
to image over 90 targets tonight and seeing stabilized around 1 arcsec.

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