Ops DAY Shift Start
TITLE: 11/19 Day Shift: 16:00-00:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Lock Acquisition
OUTGOING OPERATOR: Austin
CURRENT ENVIRONMENT:
SEI_ENV state: CALM
Wind: 23mph Gusts, 14mph 5min avg
Primary useism: 0.06 μm/s
Secondary useism: 0.56 μm/s
QUICK SUMMARY:
Detector is relocking and just got to ACQUIRE_PRMI. Wind is increasingly jumping up past 30mph, and secondary microseism is also way up due to a large storm off the coast.
16:09 I started an Initial Alignment because we started getting stuck in the ACQUIRE_PRMI -> ACQUIRE_DRMI_1F -> ACQUIRE_PRMI cycle again
16:55 We kept having locklosses, even from as far up as CARM_OFFSET_REDUCTION, possibly due to high winds (lots of gusts) and high microseism. Will try initial alignment and relocking in ~15 mins.
