                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 Rain, thunder and lightning to start the night.  Humidity was a roller
 coaster most of the night and just below closure limits (plus with
 the passing clouds it looked a bit too iffy to open).
 Finally around 04:30 the clouds no longer looked to be a threat (even
 though the humidity was hovering around 80%) and we openend.
