              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Sutherland
Restarted hub, tcc, and axis controllers.
Zeroed agile and na2 rotators.
Restarted dome mac since TUI was not responding on it. Seemed to fix the problem.
Implemented a 20 point pointing model.
Attempted polarization tests on Apollo, but the rpi5 unit wouldn't properly communicate.
Overall a pretty cloudy and dusty night. Called it quits around 4am since no more engineering tasks could be done, and forecast for the rest of the night looked bad.
