Lockloss 17:52 UTC (20:46 lock)

Lockloss at 17:52 UTC, potentially from a 6.2 from Costa Rica.

Relocking is going to be tough, given the rising microseism (getting above 90th percentile), and the winds creeping up.

Towards the end of TRANSITION_FROM_ETMX, a 1Hz oscillation started building up mainly in DHARD_P before we lost lock right when getting to LOWNOISE_LENGTH_CONTROL
