9:12 Back to OBSERVING

4:46 - 9:12 CORRECTIVE MAINTENANCE due to PSL Trip (see 36078 & 36080)

Spent a couple of hours trying to get back to OBSERVING.  Early issues with alignment noted in my Transition alog.  

Troubles in latter steps of locking.  Not certain of what the issue was.  On third (& successful) attempt, I paused at various points to check Bounce, Roll, & Violin modes.  Ultimately did not take action.

Around VIOLIN MODE DAMPING1, ASC Pitc signal gets noisy (coinciding with tidal signals for ALS x & y REFL control).  Also see ASC SRC1_Y_INMON drifting down (But reduce rf9 took care of this).

Upon getting to NLN, had a few (small, i.e. e-11 & smaller) SDF diffs (attached) related to pointing slider offsets & HEPI BS setpoints.  I simply REVERTED them.
