Just chatted with Brian and Jeremy at LLO about the start of their Maintenance time (which is usually 8amCT [13:00UTC]), and they said they are going to let L1 stay in Observation Mode beyond their usual Maintenance start time so we can have more double coincident time (they will let L1 drop out whenever activities/contractors bump it out of lock.)
(For the record, LHO's Maintenance Time starts at 8am PST [15:00UTC]).
13:32 UTC Guimin just notified me they are out of lock and starting their Maintenance.
