Ops Shift Log: 05/09/2019, Day Shift 15:00 – 23:00 (08:00 - 16:00) Time - UTC (PT)

State of H1: Locked at NLN with a range of 113.0Mpc

Intent Bit: Observing

Support: Jenne, Sheila

Incoming Operator: Niko

Shift Summary: Relocking the IFO after commissioning lockloss was a challenge. There was a bit of hand aligning PRM, SRM, and BS. Once locked at NLN, had to turn on the Squeezer Noise Eater Relay to get the Squeezer to lock. Cleared many SDF differences (aLOG #49155) to get back into Observing.

Went out of Observing a couple of times for commissioning work on the ASC Yaw oscillation problem.

Wind and microseism are elevated. All else appears normal at this time.
