Finally recovered from a lockloss after about an hour.  Wanted to avoid going through an Initial Alignment, but went through grief mainly during LOCKING_ARMS_GREEN.  ALSx looked fine but it would break lock after a few seconds/min even with WFS engaged.  Here were the details:

• 1:38 Lockloss
  • Tried to not run an alignment, but kept dropping out during LOCKING_ARMS_GREEN
  • ALSx had issues.  It would look good and then a few seconds later (w/ WFS engaged), it would slowly drop in power.
  • Took break to try to lower its polarization, but had no luck decreasing it (so it hovered around 25-28.
  • Eventually made it through LOCKING_ARMS_GREEN.  But ALSx did drop down to about 0.8.
  • After optimizing PRMI, revisited the Green Arms.  Able to get x & y arms up to about 1.08 via the TMS
  • Tweaked PRM to get DRMI/POP18 optimized
• 2:38 back to Nominal Low Noise
• 2:45 PEM injections starting up again.
