417702:15-02:2100:06Persistent HFC faults within the first 2 minutes of starting a track, sometimes after focus moves, sometimes for no reason. Problem cleared up on its own.
409902:29-02:3200:03Unceremonious abort. Was able to continue normally.
417605:27-05:3000:03Go next command would not do anything with next target loaded, much less turn green with next position loaded. No error messages displayed. When shutting down TCS processes via ctrl+c in terminal window tcs_server would not shut down. Ran top and saw that it was using 100% cpu.Killed tcs_server and restarted everything and it worked after that.

417109:43-09:4600:03After tracker slew, tracking mode is activated, On Trajectory light is green, but the tracker is not moving on a non-satellite target. Aborted, got one error message while trying to load a trajectory afterward, but was able to proceed with tests normally after that.
