              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening was cloudy with showers. Dataq needed a restart from the backend (server) side. Rain started again at 20:00, did not end until around 21:30. Radar retuns persisted all around us. Light rain started again around 00:30. Rain had ended by 01:30. There was a break in the clouds around 03:40 that allowed us a sliver of time for CG01. It soon clouded over and rain appeared on the radar again, so we closed at 04:41. We did not open again.
