Ops Shift Log: 06/20/2019, Evening Shift 23:00 – 07:00 (16:00 - 00:00) Time - UTC (PT)

State of H1: Locked at NLN

Intent Bit: Observing  

Support: N/A

Incoming Operator: Niko

Shift Summary: Lost lock early in the shift probably due to high winds and gusts. After several relocking attempts, many tweaks to the alignment, 2.5 hours, and a drop in the wind was able to relock. Now back at NLN and Observing.  

   After the wind settled down and the IFO was relocked, the second half of the shift was spent with the IFO locked and Observing. The range is sitting at 114.9Mpc from 37.2w of laser power. There is nothing out of the ordinary to report, at this time.
