OPS OWL Shift: 5.9 Oregon Earthquake Lockloss 06:47 UTC

A 5.9 EQ from Oregon hit H1 quite violently and tripped:

HAM1 ISI, HAM2 ISI, HAM2

IM1 (M1), IM2 (M1), IM3 (M1), IM4 (M1)

MC1 (M1), MC2 (M1), MC3 (M1)

PRM (M1,2,3), PR2 (M1), SRM (M1,2,3), SR2 (M1), SR3 (M1)

FC1 (M1,2,3), FC2 (M1,3)

Along with their respective ISIs (ST1) and the QUAD ISIs (though I untripped a bit too quickly to note the exact ISIs I untripped so will append this tomorrow when I can trend without lag).

A few guardians also stalled so I unstalled them. I attached an overview of verbal trips and overview screen.

IFO is back to LOCKING and EQ is mostly passed. I've reset myself as the OWL.
