                  ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: B.Ketzeback
 First half started with some orographic clouds but they cleared out about
 19:00. Rest of the night went well.
 2nd Half Observing Specialist: R.McMillan
 Shortly before midnight the wind began to gust over the limit, and
 we closed.  The wind stayed up for several hours, but we were able
 to reopen at 03:30.  Humidity rose after we opened, then leveled off
 a little short of the limit.
