                ------------- ACTIVITY LOG --------------
 Observing Specialist, 1st Shift: Noel Camron Hastings
   I opened the enclosure at 16:50 to begin cooling under partly cloudy
skies, mostly cirrus. No problems encountered.
   We closed at 20:03 due to rising humidity and threatening weather. The
clouds were moving very fast and looked unstable.
 Observing Specialist, 2nd Shift: Russet McMillan
 The clouds started to clear around 00:30, but the humidity was too
 high to permit opening at first.  We eventually opened at 01:40 to a
 few scattered clouds and poorish seeing.  Observations went smoothly
 for the remainder of the morning.
