Even after Initial_Alignment H1 was bouncing off of DRMI into PRMI & Check mitch fringes.
I requested another Inital_Alignment which went quickly.
H1 is already well past DRMI locking.

OPS OWL assistance

I got a call 05:39 UTC and found the SQZ to be struggling to lock, notifying "LO RAILING", I consulted the alog and found a report alog81027 from Vicky and myself where we faced the same issue. I checked the FC alignment and found it to be the same, I then checked the ZMs and found ZM6 to be in a very different spot, especially in pitch. I brought back ZM6s alignment which let the LO lock but our range was terrible, I then adjusted the OPO temperature and ran a SQZ ang adjust as it was reporting that the angle was out of range then everything looked good.

05:55 UTC Observing

Back to observing at 04:13 UTC. A lockloss during MAX_POWER caused violin modes to ring up, so on the next attempt H1 spent about 20 minutes damping in OMC_WHITENING. Fully automatic relock.

Saturday Ops Shift End.

TITLE: 07/05 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Lock Acquisition
INCOMING OPERATOR: Ryan S
SHIFT SUMMARY:

Lockloss first thing in the morning.
Got relocked just in time for SuperEvent S250705cb candidate!
Had another Lockloss that pushed the Calibration sweep off until later in the day due to thermalization.

Dropped from Observing for SQZ "Beam diverter is open but no 3MHz on OMC, could be an alignment problem"  Issue @ 20:31 UTC.
When I cleared the History on H1:SUS-ZM6_M1_LOCK_ filters and allowed the SQZ_MAN to do lock everything it seemed to work.
Note: Did not have to move ZM4 or ZM6 sliders to get SQZ_LO_LR back to LOCKED_OMC[20].

Thermalized Calibration measurement @ 21:39 UTC.

Looks to be some motion on ETM L3 shortly before the lockloss, but hard to say where this came from.

Lockloss & mid Shift report

Relocked from the Prior lockloss this morning.
H1 Made it to NLN and Observing by 16:25 UTC

Superevent S250705cb candidate !

17:27 UTC Unknown Lockloss

Relocking Notes:
H1 Relocked it self reaching NLN at 18:34 UTC after bouncing between Locking ALS and Down a few times.

The Plan:
Since H1 barely got back to Observing at 1830 UTC and wont be Thermalized until 21:30 UTC. I plan to drop out of observing at 21:30 to get a Calibration done here at LHO.

Ops Eve Shift Start

TITLE: 07/04 Eve Shift: 2330-0500 UTC (1630-2200 PST), all times posted in UTC
STATE of H1: Commissioning
OUTGOING OPERATOR: Tony
CURRENT ENVIRONMENT:
    SEI_ENV state: CALM
    Wind: 25mph Gusts, 20mph 3min avg
    Primary useism: 0.04 μm/s
    Secondary useism: 0.07 μm/s
QUICK SUMMARY: H1 has been locked for almost 11 hours, but currently not observing as I'm troubleshooting an issue with the SQZ filter cavity. I'm able to consistently bring everything with the squeezer up to before the FC is needed, and lock the FC up to the SQZ_FC Guardian's 'IR_FOUND' state, but every time I try moving on, the FC drops out. Investigation still ongoing.

ryan.short@LIGO.ORG - 17:32, Friday 04 July 2025 (85551)SQZ

H1 back to observing at 00:18 UTC.

Ultimately, after trying several things that didn't completely fix the issue like trending FC1/2 OSEMs, adjusting FC1/2 to maximize FC green transmission, and doing a "graceful clear history" on the filter cavity ASC, I enlisted Sheila for guidance. I ran her new 'SCAN_OPOTEMP' Guardian state to optimize the OPO temperature (then gave it a couple more steps to maximize CLF_REFL_RF6), then requested SQZ_MANAGER all the way up to 'FREQ_DEP_SQZ', which worked perfectly this time. The improvement of CLF_REFL_RF6 from 0.35 to 0.39 must have been just enough to make the filter cavity happy.

There were outstanding SDF diffs on h1ascsqzfc, possibly from my history clearing, which Sheila said were okay to just revert (screenshot attached). When I did this, I saw the green FC spot wobble, but not unlock. I then returned H1 to observing.
