                 ------------- ACTIVITY LOG --------------
 Observing Specialist, 1st Shift: Noel Camron Hastings
    The Echelle autofill system was repaired today, so we are no longer
required to manually fill it. I switched gratings out tonight from high
to medium resolution in DIS and calibrated. The observer showed up at 17:30
MST and was finished with cals by 18:25 MST, so we opened at 18:30 MST to
cool for 5-10 minutes before starting.
    Clouds hampered observations all evening with some holes to shoot
through. When we could see stars, the seeing and pointing were very good.
 Observing Specialist, 2nd Shift: Russet McMillan
 Everything went smoothly second half aside from a few hours of
 dodging clouds.  Eventually the clouds cleared, and the seeing was
 fairly good.

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