TITLE: 10/29 Eve Shift: 23:00-07:00 UTC (16:00-00:00 PST), all times posted in UTC
STATE of H1: Lock Aquisition
INCOMING OPERATOR: Austin
SHIFT SUMMARY: Two lockloss from NLN, small IR issue on the first relock, and ITMY mode8 nominal settings don't seem to be working anymore. We haven't had any locks survive for more than 3 hours since the 17:35UTC LL this morning. We reached NLN right at 06:59, we'll go into Observing as soon as ADS converges.

01:28UTC Lockloss

The first relock attempt we went through IR without actually finding DIFF_IR and so when we got to CARM_TO_TR there was "no IR in the arms", on the second try I held at FIND_IR to make sure it got it then we lost lock at TURN_ON_BS_STAGE2, third aquisition I again paused at FIND_IR and then it was a fully automated relock back to NLN.

03:15 back to Observing, the high frequency noise looks better this lock.

ITMY mode 8 has been slowly ringing up during every lock today with its current nominal settings, trending it tooks like it stopped working 2.5 days ago and has rung up each lock. The first lock I changed the sign and it started damping, the second lock it continued to rise even with the sign change, hmm. I don't think I can mess with the phase while we're in observing so I've just turned off the gain for now.

05:51 Lockloss right at the 3 hour mark, we were riding out an earthquake, SEI had returned to calm about 20 minutes earlier but ground motion was still elevated.
