Incoming Operator: Jim

Activity Log:

7:00 IFO locked. Intent bit commissioning. Jeff K. updating filters, Stefan and Evan working on calibration and OMC mode matching. Sorry I forgot the transition summary.

7:36 Intent bit set to Undisturbed.

7:49 Briefly went to commisioning to close the beam diverter before I realized it was already closed.

14:00 Lockloss due to 4.7M earthquake in Lakeview, Oregon. Only SUS OMC SW watch dog tripped.

14:28 Locked again at NOMINAL_LOW_NOISE. There's a tall peak around 18 Hz (another roll mode?). I watched to make sure it's being damped before setting intent bit to Undisturbed.

15:00 Handing off to Jim.
