Submitter:

Observer Support: 
Jacqueline Seron
Night Assistant: 
Alberto Alvarez
Also Present: 
Jeremy Mould, Humberto Orrego, Hernan Tirado (by phone)
Problems: 

At 3:38UT: INTERLOCK_SISPI and INTERLOCK_ICS faults triggered.  (The first Alarm, at 03:38:47, was regarding DONUT, but AOS was turned OFF so I don't know what that means.)  SISPI would not reconfigure despite repeated attempts.  system1 reset brought things back.  But...

At ~4:30UT: TPOINT would not agree with the TCS regarding the non-sidereal tracking (I think, more details should be obtained from Alberto or Humberto - I'm not sure what they did to bring things back, but the TCS was restarted at least twice).

Total time lost: 3 hours
