              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend
Power flashed at 22:24.
Dataq was frozen again so I powercycled with netswitch (did not need to reconnect TCP/IP).
We were surrounded by storms most of the night but only got a little bit of rain. We didn't open.
