OPS OWL report

I can't get past FIND_IR consistently, the last attempt COMM was doing nothing so I found it by hand then it was stuck in an endless cycle of "found seomthing, sleeping for 5 seconds". Next attempt was successful but there were no flashes on DRMI, went to CHECK_MICH which offloaded, still no flashes. I brought PR3 back to where it was and still didn't get any flashes and we went back into CHECK_MICH which again finished, then we were able to lock PRMI but not DRMI, got PRMI again then lost lock. I'm going to send out some calls for help now. Keita said he's going to check it out.

Made it up to CARM_TO_TR then lost lock, looks like greens arm wfs oscillated then killed it? Guardian was stepping up the LSC_REFL_SERVO_IN2GAIN as we lost it. Happened a 2nd time in the next attempt, hard to tell whats losing lock first, DRMI or green arms.

We made it to CARM_150_PICOMETERS and the IN2GAIN was fully stepped down to its -30 value then we lost lock as we were about to go to DARM_TO_RF

Weird PRCL oscillation/glitches that shows up during these CARM locklosses, which seem to be from the CARM gain reduction.
