                  ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: J. Barentine
 Opened at 20:00 under partly cloudy skies with rain in the region, but
monitoring the cloud camera very closely.  Closed at 21:35 after Craig
called to report rain on Sunspot Hwy not far from APO.  Reopened at 22:40
to what looked like clearing from the west only to be foiled by a sucker
hole.  An orographic cloud mass hung out over the mountain for the
remainder of the first half, and Jon decided to call it a night around
00:15 and gave the remainder of his time over to Atsuko.
 2nd Half Observing Specialist: J. Dembicky
 Clouds prevented opening on time but they quickly moved out around 01:30
when we re-opened.  Everything ran smoothly.
