Tony had a lockloss that the lockloss tool tagged with a DCPD saturation (our 11 most recent NLN locklosses have been too) 1372544545.
Waited ISC_LOCK waited 20 minutes in OMC_WHITENING for lots of violins to damp. The VOILIN_DAMPING guardian had turned down the gain on EY08 as it was rung up but the damping OUTMON reduced quickly <100 so I increased the gain back to it's nominal for faster damping. Lots of voilins are still rung up and slowly damping, see attached.
SQZ_MANAGER had message "SQZ ASC AS24 not on??" so I took SQZ_MANAGER to NO_SQUEEZING, gracefully cleared the A42 history (sitemap > SQZ > SQZ Overview > IFO ASC > ! graceful clear history) and then SQZ_MANAGER to FREQ_DEP_SQZ. This has happened a couple of times recently 70890 but Vicky and Naoki plan to look into this or automate this week. Tagging SQZ.
It seems the OMC_DCPD tag has only been on the last locklosses since the violins have been rung up (2023/06/29 70945, 70943), see attached. The OMC overflows H1:FEC-8_ADC_OVERFLOW_0_{12,13} haven't dropped back down to zero and the lockloss tool just looks for these channels being non-zero before the lockloss.
This 22:22UTC lockloss has an unknown-for-now cause. Nothing in ASC, LSC, no violin saturations or PIs, not the IMC.
