The squeezer ASC was misaligning the squeezer early in the lock as it has been doing this week.
Ryan took us out of observing to deal with this and the roll mode. I went to no squeezing and reset the AS42 offsets for no squeezing, a little more than 1 hour after power up. These offsets have changed with thermalization in the past.
I reset the sqz ASC using the "graceful clear history". Once the squeezing was injected the RF3 level was too low to lock, so I adjusted ZM6 manually. I could perhaps have done this (without reseting the offsets) by asking SQZ_MANAGER to RESET_SQZ_ASC, as Oli and Camilla suggested last night.
I accepted the offsets in the observe.snap, but forgot about the safe.snap. Ryan verified that SQZASC is not included in SDF revert, so this will be fine for the weekend, but we should accept these in safe.snap sometime soon.
If we have another lock today we can see if reseting the offsets has helped with the asc issue during thermalization. If we do not, we can set the flag to not run sqz ASC over the weekend.
