Lockloss @ 20:26 UTC - link to lockloss tool
This would appear to be another FSS-related lockloss, as evidenced by the fact that the IMC and arms lost lock at the same time, we see some glitches in the FSS fast channel, and nothing else jumps out to me for another cause.
H1 back to observing at 22:04 UTC. I needed to adjust SRM slightly to lock DRMI, but otherwise a fully automated relock.
