                  ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: C.Hastings
  Clouds, wind, snow, ice, closed. Dome found to have ice and snow
  encrusted into all the grooves and surfaces, remained closed despite
  any other conditions. I left the dome pointing to the south.
 2nd Half Observing Specialist: R. McMillan
 Second half was mostly clear with lighter winds for a few hours, but
 the telescope remained closed due to ice on the roof.  Winds
 increased again near morning twilight.
