Ops Shift Log: 08/10/2019, Day Shift 15:00 – 23:00 (08:00 - 16:00) Time - UTC (PT)

State of H1: Locked at NLN, 114.5Mpc range

Intent Bit: Observing

Support: N/A

Incoming Operator: Niko

Shift Summary: 2 GRB Alerts – Both good trigger duration and latency. All detectors observing. Stopped injection, spoke with LLO and did a 60 minute stand down.

   Had some issues with the Squeezer conversion efficiency, which effected the range. Although it has not corrected itself, it is improving and as such, the range is improving.

   Had several Saturday site tours come through the control room.
