Observing 1728 UTC.

I adjusted the ALSX fiber polarization after the first few lock losses that happened before we could get off of green. We then had a few lock losses on our way up at various places, but eventually made it all the way up.

I still haven't found any clues about the last lock loss. It seemed pretty sudden, and I'm not seeing much reaction from ASC and very little from LSC only about ~0.1 before we lose lock. The FSS seemed to be good for this lock reacqusition, and wasn't the cause of the lock loss either.
