Ops Eve Shift Start

TITLE: 07/01 Eve Shift: 2330-0500 UTC (1630-2200 PST), all times posted in UTC
STATE of H1: Preventive Maintenance
OUTGOING OPERATOR: Corey
CURRENT ENVIRONMENT:
    SEI_ENV state: CALM
    Wind: 18mph Gusts, 11mph 3min avg
    Primary useism: 0.02 μm/s
    Secondary useism: 0.05 μm/s
QUICK SUMMARY: H1 has just relocked following the maintenance period today, but currently waiting in OMC_WHITENING to damp some very rung-up violin modes. Meanwhile, Elenna is running jitter noise injections. I'm also aware of the OPO crystal move from today, so I'll be watching SQZ performance this evening and will adjust the temperature if need be.
