Lockloss @ 20:52 UTC
Lockloss @ 20:52 UTC after just under 15 hrs locked - link to lockloss tool
No obvious cause.
Ran an initial alignment doing PRC align by hand, then main locking was fully automatic.
Once at low noise and before observing, I noticed SQZ looked poor, and the SQZ BLRMs were worse than at the start of the last lock stretch. I cycled SQZ_MANAGER through 'SCAN_SQZANG_FDS' to try and find a better SQZ angle, but the Guardian wasn't able to find a place that made the BLRMs and BNS range both look good, so I manually searched around at different angles and eventually settled on 139 with a "cleaned" range of 153Mpc. Started observing at 22:34 UTC.
