Lockloss due to 5.7 EQ in Mongolia. Initially I thought we rode it out since the EQ happened since verbal sounded it 30 minutes before losing lock. Though looking at the later arriving R waves, we seem to have lost lock 3 minutes after they were detected by ISI Sensors, microseism FOM and Picket Fence. Right after the LL, EQ mode activated. High secondary microseism likely contributes to higher EQ susceptibility too.

Shall begin to re-lock once it passes.
