OPS OWL report

We lost lock and several suspension have tripped from a 5.7 from Northern Mexico. There are DACKILLs on both the ITMs, this needs a model restart I believe to fix, we are going to be DOWN for the rest of the OWL shift at least. I'll call out for help in a bit, after 6.\

The microseism is also increasing, so I'm not so sure we'd be able to relock.

ITMX,ITMY -SUS, ISI, HEPI were all tripped.  I have reset all the watchdogs and and ITM spots have returned to the camera screen.  Will let the operator check the health of the system before moving on.
