              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
We started out with thunderstorms. Rain on and off for the night, ending around 22:00.  Thereafter, rain close on radar kept us closed. We used the time to do tests on the teriary rotation. Weather did not improve, radar returns persisted all night. We did not open.
