Ops Eve Shift Start

TITLE: 11/19 Eve Shift: 0030-0600 UTC (1630-2200 PST), all times posted in UTC
STATE of H1: Preventive Maintenance
OUTGOING OPERATOR: Ryan C
CURRENT ENVIRONMENT:
    SEI_ENV state: USEISM
    Wind: 10mph Gusts, 8mph 3min avg
    Primary useism: 0.04 μm/s
    Secondary useism: 1.47 μm/s
QUICK SUMMARY: Due to very rapidly rising microseism, H1 will not be locking this evening or overnight, which allows us to run a long test for PSL glitch hunting by leaving just the PMC locked (no FSS, ISS, IMC). The DB37 cable was unlplugged from the FSS fieldbox at 23:45 UTC.
