TITLE: 05/04 Eve Shift: 23:00-07:00 UTC (16:00-00:00 PST), all times posted in UTC
STATE of H1: Observing at 155Mpc
INCOMING OPERATOR: Ryan S
SHIFT SUMMARY:
IFO is in NLN and OBSERVING (26hr 46 min lock)
Violin Ring-Up:
From 04:40 UTC to 05:14 UTC, went in and out of observing to try to damp violin ETMX mode 9. The nominal gain did not work nor did testing different gains and (and turning on the angle filters). Checked the wiki/alog also but to no avail (initially went to the violins wiki page and Rahul's ppt to go to damp simple when Guardian was fighting me with gain issues). This violin has been growing slowly since the lock acquisition 26 hrs and 39 minutes ago. (screenshot). During this time, the violin count magnitude increased seven fold. Pinged Rahul and expecting help with it tomorrow.
SQZ Unlock:
Squeezer unlocked at 05:20 UTC but managed to relock at 5:29 UTC. I did have to play around with guardian states because guardian notified me that the SQZ ISS had saturated and to go to alog 70050 from May 2023. As I was playing around with the states, the SQZ relocked automatically. SQZ lockloss was potentially caused by a time corellated local earthquake that showed up on the EQ peak_outmon very sharply but was not high magnitude enough to cause us to go into EQ mode.
