              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend
Thunderstorms this afternoon. Dataq was stuck with "Please wait for device reconnect" again when I came in.
Scattered showers that brought in lots of clouds but not much precipitation kept us closed. The radar cleared up right around changeover and we got on sky at the start of B-half for a few hours before humidity got too high and we had to close back up. It did not improve.
