EQ Lockloss (M6.1 @Japan)

Almost thought there was a chance we were going to ride through this earthquake (L1 went down 14 min before us), but alas the ground motion was too much for H1 and caused a lockloss.  This ended a nearly 6.5hr lock for today's shift.  Observatory Mode is in the EARTHQUAKE state until we get back to NLN.  Will Stay in Prep For Locking for atleast 30more min.
