STATE Of H1: Observing

SUPPORT: N/A

LOCK DURATION: ≈5 hrs

INCOMING OPERATOR: Nutsinee

END-OF-SHIFT SUMMARY: There was a mysterious lockloss ≈7 hrs ago and I had some trouble re-locking (see activity log). After that, smooth sailing. Handing off to Nutsinee.

ACTIVITY LOG:

17:02  Robert into LVEA to install shaker

16:57  LockLoss

17:30  went 20 minutes trying to get PRMI locked. Ditched and went to initial alignment

17:56 Chris called to tell me he was leaving in a few to go doen X-Arm to do beam tube work. Joe will accompany.

18:15  First attempt at relocking failed. Problems with Y-arm and diff vco. Re-visited Y arm alignment. H1:SUS-ETMY_M0_LOCK_Y_OUT16 took a rather long time to decide where it wanted to settle down.

19:00  OMC locked on wrong mode: After playing with OMC guardian and LOCK_00, then tripping the OMC watchdog and having to request align a few times, I got OMC back locked on the proper mode. 19:18 NOTE TO SELF: make sure that after manually locking OMC to advance the OMC Guardian node to “READY_FOR_HANDOFF” before manually pushing DC_READOUT. D’OH!

19:58  Re-locked at NLN

20:01  set intent bit to Undisturbed

00:00 Set intent bit to Commissioning for Robert to do some injections. This is being done in cooperation with Livingston.
