Ops Shift Log: 07/29/2019, Owl Shift 07:00 – 15:00 (00:00 - 15:00) Time - UTC (PT)

State of H1: Locked at NLN, with 116.3Mpc of range from 37.2w of laser power  

Intent Bit: Observing

Support: N/A

Incoming Operator: TJ

Shift Summary: With the exception of one lockloss in first part of the shift, the IFO was locked and observing for the Owl shift. Lockloss recovery went well. I had to help ALS-Y with locking, but all other parts of the initial alignment and relocking happened without operator intervention. Current environmental conditions are good and there are no outstanding issues or problems to report.
