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.

Lockloss @ 23:26 UTC after almost 5 hours locked - link to lockloss tool

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

FAMIS 26401, last checked in alog85398

All fans largely the same as last check and within noise thresholds, aside from a very small increase in noise for MR fan 1.

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.

SHIFT SUMMARY: Started the shift by troubleshooting a SQZ issue that once resolved made for a straightforward evening. Two locklosses tonight, but relocking each time went automatically. H1 has now been locked and observing for almost 2 hours.

• 00:18 - Resumed observing after fixing squeezer
• 00:45 - Lockloss - alog85552
• 02:09 - Observing
• 02:10 - Lockloss - alog85553
• 03:17 - Observing

Lockloss @ 00:45 UTC after almost 12 hrs lock - link to lockloss tool

No obvious cause.

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.

• Wind moderate, microseism low
• All other systems nominal

SHIFT SUMMARY:
H1 has been locked all day and is still locked at NLN.... But...

Dropped out of Observing at 22:54:25 UTC due to the SQZ_FC  Dropping to Down.
A few trys later it locked and H1 returned to Observing for just a second, only for the SQZ_FC to unlock again. @ 22:58:55 UTC.
Several trys after that and the FC cannot seem to lock it's self reliably. 
We have tried following the directions found in the SQZ_FC section of this SQZr Troubleshooting document.

Things i have done already.
Init SQZ_LO_LR & then SQZ MANAGER
