QUICK SUMMARY:
H1 Is Currently Locked at NLN {600} But not Observing due to a SQZ_SHG issue:
Error SQZ_SHG [LOCKED.run] USERMSG 0: PZT voltage limits exceeded.
Sheila is currently working on the issue.
Sheila Fixed the issue, I have attached soem pictures to help future Ops that find this issue:
Sitemap -> SQZ -> SQZ_OVERVIEW -> SQZT0 -> PZT -> Move H1:SQZ-SHG_PZT_OFFSET slider.
We Now have a "pump fiber rej power in ham7, nominal 35e-3, align fiber pol on sqzt0" error message on SQZ-OPO_LR. nopted will do tomorrow.
Then we took SQZ_ANG_ADJUST Guardian to ADJUST_SQZ_ANG_ADF [10] which kinda worked but didn't improve sqzing and reverted back.
I then accepted the SDFs and now we're back in Observing at 00:07:25 UTC.
