OPS Monday day shift summary

TITLE: 12/25 Day Shift: 16:00-00:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Observing at 150Mpc
INCOMING OPERATOR: Oli
SHIFT SUMMARY: We stayed locked for most of the shift, 1 lockloss. Locked and observing for ~6:30 as of 00:00UTC

16:41UTC Lockloss after only 36 minutes, using 'guardctrl log -a "12/25/2023 16:38 UTC" -b "12/25/2023 16:42 UTC" DIAG_SDF' it seems the SQZer lost lock first. Automated relock

Xarm has been locking at higher power than usual, ~1.2

I also set ITMX mode 12s gain and max gain to 0 in lscparams as its been ringing up the past few locks and reloaded ISC_LOCK and VIOLIN_DAMPING.

I did a quick walkthrough of the OSB, Staging building, LSB, and LExC and saw nothing of note.
