Lock loss 0811

1425715885

This lock loss from 15 hours ago had a rather large ETMX glitch that caused the lock loss. Upon returning to low noise, the violins were rung up. There was no earthquake during that time, but there was a lock loss from Resonance [410] during reacquisition. The violin modes that were rung up, are still damping  ~15 hours and two lock reacquisitions later. I'm not sure if the lock loss itself caused them to ring up, or the fall from the Resonance state.
