Lockloss @ 17:57 UTC - link to lockloss tool
Usual signs of an ETMX glitch on this lockloss, otherwise cause not obvious. Ends lock stretch at just over 4 hours.
H1 back to observing at 19:41 UTC. Helped PRM and SRM during DRMI locking, but otherwise the process was automatic.
I also loaded VIOLIN_DAMPING to take in the new ETMY mode 20 damping setting (gain of 0).
