  • All SUS Watchdogs tripped, but the SUSs looked OK except for the stuck ITMX.
  • Damped the SUSs (except ITMX)
  • IMC automatically locked
  • Turned off the damping of ITMX and shook it only with the pitch bias -> Easily unstuck -> damping recovered -> realignment of the ITMX probably necessary.
  • Done.
