Ops Shift Log: 09/01/2019, Owl Shift 07:00 – 15:00 (00:00 - 08:00) Time - UTC (PT)

State of H1: Locked at NLN, Range = 118.2Mpc

Intent Bit: Observing

Support: N/A

Incoming Operator: Niko

Shift Summary: A little after mid-shift, IFO lost lock following DCPD & HTTS glitches. Started relocking. Had to tweak ALS-Y to get green locked. Then at DRMI_1F/PRMI alignment did not look so good. Ran through Initial Alignment. Subsequent relocking went well, making it to NLN on the first try. Back into Observing.
