I then reset the hardware Tracker Display Panel, multiple HFC Faults. I killed -6 The GUI and all processes on the guider@htcs computer and started them up again.It repaired the problem. This same thing happened twice now. The same happened at the start of Tracker, with the same HFC Fault. I did the same this to repair. 05:50 UT -07:02 UT/ Jim Fowler was called twice. The same thing on 08:05 -08:14 UT, 08:33 -08:35 UT and 10:25 -10:30 UT. All three of these were consistent with HFC faults and were automatically aborted by the TCS GUI.
