                ------------- ACTIVITY LOG --------------
 Observing Specialist, 1st Shift: Noel Camron Hastings
   No troubles tonight. Opened at 17:05 MST to begin cooling. Found a
stuck emergency stop switch, PR submitted.
 Observing Specialist, 2nd Shift: Russet McMillan
 A command collision with DIS at the transition between first and
 second half caused a delay of about 15 minutes, but I was able to
 spend part of that time focusing so it was not entirely lost.  DIS
 recovered with only a little trouble and the affected image was
 rescued on disk.  Observing went smoothly after that, aside from the
 very bad seeing and high wind gusts which caused us to close shortly
 before 0200.  The wind just got worse as the morning continued, with
 some gusts over 50 mph, so we never reopened.
