Not a straight forward relock. I couldn't get green to lock without having to move the TMSs so I went to do an initial alignment, but then the fiber polarization was >20% on the Y laser. After adjusting that and moving through IA, MICH would not dark lock. The alignment looked really good but it still would only lock bright. The dark offsets didn't look great so I ran the scripts for that hoping it might help. Then INPUT_ALIGN refused to lock. This is exactly what happened after the harmonic oscillator was replaced recently so I was getting worried, but bumping up the LSC XARM gain eventually worked. I couldnt bring the gain back down or it would kick the IMC and lose lock. After this the rest of IA went well, and locking was no problem.

Bounce is damping slowly but we are back to observing.
