Ops Owl Shift Update
H1 has been having a hard time locking tonight due to very high microseismic motion. Unlocked at 05:43 UTC (lockloss tool) and has been down since; highest state I've seen H1 reach is TRANSITION_FROM_ETMX, alignment doesn't seem to be the problem.

Since H1 hasn't had any success locking and the microseism doesn't look like it's going to come down anytime soon, I'm leaving H1 in DOWN until the morning when hopefully conditions will be better.
