                ------------- ACTIVITY LOG --------------
 Observing Specialist, 1st Shift: J. Dembicky
 Lt. snow and clouds prevented telescope cooling.  Inspection of the
 enclosure roof revealed about an inch of powder snow remaining at
sunset.
 The snow tapered off around 05:30 but the clouds remained with the
 outside humidity also rising above the closure limits for the majority
 of the evening. We also had light snow off and on during the first half.
 Observing Specialist, 2nd Shift: Noel Camron Hastings
  Closed tonight due to snow on roof.
