                ------------- ACTIVITY LOG --------------
 Observing Specialist: Russet McMillan
 High clouds all night hampered work.  I managed to get one
 Shack-Hartmann measurement to confirm that collimation was
 acceptable (it wasn't ideal, but the telescope was still a little
 warm at the time, and later the clouds were too thick).  Ranging on
 the moon was not possible, but we did some in-dome work and managed
 with difficulty to align the IR spotting camera in thinner patches
 of clouds.

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