              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The night started off with some storm clouds to the NE but we were able to open shortly after sunset. The clouds starting building after midnight and radar was showing precipitation appear quickly.  Given the speed the precipitation was appearing on radar, I was overly cautious and closed at 00:28.  We were able to reopen during an open patch of precipitation but then closed again at 2:54 when moisture was indicated on the radar. We were not able to open the rest of the morning due to rain.
There was a Motion Error in the NE (az=107) during checkout but, aside from that, no problems tonight.
