Lockloss

Lockloss at 2025-09-19 15:19 UTC. We were waiting for an earthquake to come through - we had just entered earthquake mode and I had taken us to Hi ASC Gain mode because it looked like we might need that, but we lost lock. Checking now if the ASC hi gains is what caused the lockloss because it wasn't the ground motion

The lockloss seems like it happened 5 seconds after we finished transitioning to ASC Hi Gain, so I''m not sure what caused this lockloss. You can see the ground motion was not very high
