                  ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: J. Dembicky
 Started cooling (fans on) at 16:30, opened enclosure at 16:50.  UW was on
 the sky by 17:08 to start taking eveing twilight flats.
 Everything ran smoothly for the first half.
 2nd Half Observing Specialist: R. McMillan
 After an hour or so of poor seeing around midnight, the image quality
 improved to subarcsecond for the remainder of second half.  Thin
 clouds moved through off and on without causing significant loss of
 throughput.  Everything worked well, except for repeated crashes of
 the remote observer's Remark.  Since she was using SPIcam, she was
 comfortable operating from an mcnode and we didn't bother much over
 the problem.
