              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Delayed opening due to verga seen at sunset and threatening looking clouds and radar returns.  Skies improved around 01:15 and I opened around 01:40. We still had a radar return to our west but it was to the west of Las Cruces so no immediate threat.
Closed at 03:30 due to a storm cell approaching us from the SW.  Lt. rain around 04:15 as well as the wind gusting to around 40MPH
