Ops EVE Shift End

TITLE: 12/10 Eve Shift: 00:00-08:00 UTC (16:00-00:00 PST), all times posted in UTC
STATE of H1: Observing at 158Mpc
INCOMING OPERATOR: Austin
SHIFT SUMMARY: Currently Observing and have been Locked for 1.5hours. One lockloss during shift while I was running a Simulines measurement, so not sure if that could have/did cause it?

I have just left the ITMY Mode5 gain as 0 since it seemed like whenever I tried to change it, it would cause mode 5 to jump up and would take hours to get back to where it was before I turned on the gain. Mode 5 slope after changing gain from 0 -> -0.01 seemed to stay the same as well, and it seems like it takes a few hours after relocking for mode5 to start coming down.
LOG:

-- Relocking --
00:00UTC Detector relocking at ACQUIRE_DRMI_1F
    - I manually took us state-by-state between LOWNOISE_ASC and TURN_ON_CALIBRATION_LINES due to TRANSITION_FROM_ETMX causing multiple locklosses for Ryan C earlier in the day (74704, 74703).
00:42 Reached NOMINAL_LOW_NOISE
