Lockloss @ 00:18 UTC - PI mode 24
Lockloss @ 00:18 UTC - link to lockloss tool
PI mode 24 rung up 90 minutes into the lock stretch and caused this lockloss. I tried manually damping after seeing Guardian be unsuccessful, but I also wasn't able to find a phase which brought this mode down at all before losing lock (I did not get to trying different gains).
H1 back to observing at 01:18 UTC. Fully automated relock.
