LVEA: Laser Hazard IFO: UnLocked Intent Bit: Commissioning All Times in UTC (PT) 23:30 (16:30) Take over from TJ 23:30 (16:30) Relocking the IFO 23:52 (16:52) Locked at NOMINAL_LOW_NOISE, 22.7W, 68Mpc 00:02 (17:02) Lockloss – commissioning activities 00:36 (17:36) Locked at NOMINAL_LOW_NOISE, 22.7W, 68Mpc 00:38 (17:38) Lockloss – commissioning activities 01:09 (18:09) Locked at NOMINAL_LOW_NOISE, 23W, 68Mpc 01:10 (18:10) Lockloss – commissioning activities 01:31 (18:31) Locked at NOMINAL_LOW_NOISE, 22.9W, 63Mpc 01:47 (18:47) Set intent bit to Observing, 22.9W, 69Mpc 02:25 (19:25) Set intent bit to Commissioning – Evan working on noise characterization 03:05 (20:05) Range bump (over 80Mpc) due to calibration work 05:13 (22:13) Lockloss – Commissioning activities 05:30 (22:30) Adjust ISS diffracted power from -2.02v to -2.00v – diffracted power now at 8.4% Shift Summary & Observations: - Attend all hands meeting until 23:20 (16:20) - Evan working on noise characterization - Over 80Mcp range bump due to calibration work – NOT REAL - At the 05:13 Lockloss, the OMC watchdog tripped 4 seconds after the Lockloss - The first part of the shift was given to the commissioners while LLO was down. After LLO came back up and was in Observing mode, LHO switched to Observing mode as well. We had a 4-hour lock stretch in the middle of the shift with good range, moderate wind, no significant seismic activity. After losing lock, commissioning work continued until the last hour of the shift. Balance of the shift was spent relocking and doing fine tuning commissioning.
