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

State of H1: Locked at NLN

Intent Bit: Commissioning/Calibration

Support: Jenne

Incoming Operator: Niko

Shift Summary: IFO relocked after the Dolphin crash. Cleared many SDF Diffs (aLOG #49112) and went back into Observing. Mid shift dropped out of Observing while Jenne worked on the ASC Yaw oscillation. Took the opportunity to reload the HIGH_FREQ_LINE Guarding node for Pep. Lost lock shortly after going back into Observing.

 

Relocked and back into Observing for a short time, then turned the IFO over to Jeff K. for calibration work. Lost lock a few minutes later.

 

While working on relocking Jenne discovered PR3 was not aligned, which she corrected. Ran an Initial Alignment, and tried relocking again. After several different Guardian steps lock losses, made it back to NLN.  Accepted the SDF differences and went back into Observing.

 

Held in Observing for about 15 minutes, and then turn over the Jeff K. for calibration work.
