                ------------- ACTIVITY LOG --------------
 Observing Specialist, 1st shift: Noel Camron Hastings
  Worked with Jeff Morgan on temperature sensor mapping and calibrating
first part of the evening. I did get to open at 21:30 under windy,
partly cloudy skies. I found the pressurization fan switch in the OFF
position, I returned it to the AUTO position.
  We started by rotating the tertiary to the TR1 position with no
tertiary error messages encountered. Later, we slewed with no rotator
troubles that I could detect.
  Skies cleared dramatically around 23:00 and we successfully obtained
useable Shack-Hartmann data. We then spent some time imaging with the
guider to make sure the rotator was tracking happily when I turned over
to Russet.
 Observing Specialist, 2nd shift: Russet McMillan
 The clouds returned and the telescope was closed due to rising
humidity shortly after midnight.  We had some trouble with the GPS
clock, but it recovered itself after a few hours.  The new rotator
motor seemed improved, but still showed a few minor examples of
misbehavior.
