Ops Shift Log: 11/15/2019, Day Shift 016:00 – 00:00 (08:00 - 16:00) Time - UTC (PT)

State of H1: Locked at NLN, with 105.6Mpc of range

Intent Bit: Observing

Support: N/A

Incoming Operator: Niko

Shift Summary: IFO broke lock twice during the shift mostly due to wind fence activity. It took many tries to relock from the second lockloss. The cementing of the poles for the wind fence is finished at both ends. The crews may have some more cleanup but the pole and cement work is finished.

Microseism is still high (0.6um/s) but is in a downward trend.
