              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Humidity kept us closed at the start of the night.  It seemed to stabalize around 85% and I decided to open aroudn 19:30.
Around 02:10 the wind gusts became high enough that we needed to close.  We did not re-open the remainder of the night due to high wind gusts.  I gave up at 05:30 with wind gusting still over 40MPH.
