              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening start partly cloudy, with storms at a distance moving toward us.  We opened at sunset regardless to take advantage of a hole.  Conditions stayed partly cloudy to mostly clear through until 3:30 at which point thicker clouds came in.  Rain was getting close to us, and the observers were getting no useful data, so we closed at 03:40. We did not open again.
