TITLE: 08/27 Eve Shift: 23:00-07:00 UTC (16:00-00:00 PST), all times posted in UTC
STATE of H1: Observing at 154Mpc
INCOMING OPERATOR: Tony
SHIFT SUMMARY:

- Arrived with H1 locked for 17.5 hours

- 0:21 UTC - ISS pump turned off, followed alog 70050 to troubleshoot

• Reconciled, saved the OPO temp SDF here, back in OBSERVE @ 0:34 - Tagging SQZ

- Lockloss @ 1:08

- Relocking was troublesome, had to tinker a lot with ALS Y to try and find light on the PD. After a few slider restorations and trial/error attempts later, I was finally able to get it to catch. Writing down the golden sus values here for future reference:

• ETMY P: 135.2 Y: -160.8, TMSY P: 66.2 Y: -280.9, ITMY P: -10.7 Y: -17.1
• Seeing a slight swing in temps at EY, but nothing too egregious and looks to have tapered off - Tagging FMCS, scope attached

- Rest of unlocking went unaided, acquired NLN @ 2:38, OBSERVE @ 2:54

• Attaching some SQZ SDF DIFFS, these were caused by me accidently reverting the wrong suspensions trying to do a sus revert. Will be reverting all these changes - 1 / 2 / 3

- 102 Hz peak is apparent for this lock, screenshot

- EX saturation @ 4:43/5:07

- Microseism looks to be on the rise, but otherwise all looks nominal. Setting H1 to managed to handing off to Tony for the night.
