Notes from locking this morning (with Alignment woes and Transition from ETMx locklooses)
After spending 3hrs trying to get through an alignment yesterday afternoon, and since H1 was having issues after this morning's lockloss and multiple Initial Alignment cycles (and also after talking with TJ [owl shifter]), decided to REVERT all suspensions (except squeezer) to a time before last night's lock.
Chose time when ISC LOCK was in the Alignment state (#11) and picked a time within a minute of the end of when it was in this state. (Still not sure if that is the best way to pick a time, because how would one know if ALL sus were in an "aligned" state.) So---I reverted to the following time:
Alignment #1: Going for a Manual Alignment to slowly go through each alignment state since some states are broke.
Lock#1: Selected PRMI (locked within 15sec), but had a lockloss at Transition From ETMx.
Then there were several early-state locklosses.
Had another Transition From ETMx lockloss at 1719utc (note: during this lock and before the lockloss, Jim brought the BRSx back in-loop (at 1656utc)---we hadn't been using it for the last day or so.).
Finally, H1 made it to NLN at 1805utc.
After lockloss from a 2hr44min lock, H1 had issues with early-state locklosses. It also ended up looking misaligned via a dead DRMI acquisition. So ran CHECK MICH FRINGES + PRMI (which needed PRM tweak). DRMI also needed SRM yaw-tweaks. After this H1 returned to our old friend Transition From ETMx and had a lockloss here (3rd time this has happened today).
For recent locking, the Y-arm was not locking. So it automatically went through a round of INCREASE FLASHES (which took a long time) and resulted in a not very great alignment with flashes much lower than what one could get by tweaking by hand when Unlocked---which is what I ended up doing. (It feels like with winds above 10mph the green arms have been having issues sadly.)
