                  ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 We were delayed a little in getting on the sky by last-minute
 adjustments to the new guider, but eventually we were able to make
 use of the very fine seeing.  Small clouds came and went throughout
 the night, interfering with some tasks but never making work
 impossible.  Everything went very smoothly.
 Tasks completed: primary collimation, secondary fine-collimation
 according to Shack-Hartmann, tertiary tilts for three instrument
 ports, confirmation of guider functionality, guider focus, guider
 instrument block, pointing model.

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