The summary pages report 18h of lock in low noise with an average of 65 Mpc (WOW!). I believe the longest lock of the aLIGO era is the 30h long lock of L1 (no pressure! :-) However, I think this H1 lock now sets the new record of the best time-volume lock ever, equivalent to about ~26 days of eLIGO @ 20 Mpc.
LIKE! I have the remote MEDM screens. I've been stalking. :) The only bummer is, it looks like coincidental locking time isn't quite as good.
