              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Sutherland
Restarted dataq at the start of the night. Restarted again around 8pm. And again around 10:30pm. Again at 10:45pm. Again at 6am. Sigh.
Observer got kicked off of TUI at 8:21pm seemingly randomly.
Opened at 10:22pm. Closed for incoming weather at 1:45am. We never reopened, and we gave up for the night at 5:45ish.
Some data got taken, but clouds and nearby radar returns were a constant pest through the night.
