              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Sutherland
Dataq system was having trouble connecting. IP manager is down, but it looks like dataq is still running?
Gcam needed restart at start of night.
OU01 couldn't see through the clouds, and gave up at 00:45, ceding the rest of their time to NM04. Unfortunately, NM04 also struggled with clouds. We gave up around 5:15am.
Precip got on the mirror around 2am unfortunately. Weather status and radars all looked fine but the precip alarm went off while the dome was open. Sorry :(
TUI disconnected at 3:09am. No power flicker or anything that I noticed.
