TITLE: 06/26 Eve Shift: 23:00-07:00 UTC (16:00-00:00 PST), all times posted in UTC
STATE of H1: Observing at 137Mpc
SHIFT SUMMARY:

- H1 had a power glitch, but has since been recovered

- During an IA post recovery, I have to move SRM by 20 ur in P, and 13 in Y to get SRY to catch - something we haven't had to do for a bit

- Lockloss - due to commissioning error

- Upon relocking - I had an issue not getting any light on ALS X. After trying to move the EX sus to no avail, I tried doing a slider revert for ETMX and TMSX to the last time green arms were locked - no dice

• Elenna and I noticed that something was driving the beam on the ALS X camera very irratically, we also saw that the ETMX L1/L3 stage was saturating on the SUS saturations overview
  • ALS X guardian was in UNLOCKED and ISC LOCK was in GREEN ARMS MANUAL so we were unsure what could have caused this driving of the suspension
  • After running an INIT on ISC LOCK - the saturating stopped
  • Flashes were still poor, but after walking the EX suspensions in P/Y, I was able to lock ALS X and move up ISC LOCK  - Tagging ISC

- Held at OMC whitening to damp violins for ~10 minutes

- Acquired NLN @ 1:22, OBSERVE @ 1:23

- S230627c @ 1:53

- EX saturation @ 2:55

- Leaving H1 to Camilla with H1 still going strong :)
