Ops Eve Shift Start

TITLE: 06/23 Eve Shift: 2300-0800 UTC (1600-0100 PST), all times posted in UTC
STATE of H1: Observing at 156Mpc
OUTGOING OPERATOR: Corey
CURRENT ENVIRONMENT:
    SEI_ENV state: CALM
    Wind: 7mph Gusts, 4mph 5min avg
    Primary useism: 0.02 μm/s
    Secondary useism: 0.17 μm/s
QUICK SUMMARY: H1 has been locked for almost 4 hours. After I arrived, the OPO pump ISS saturated and dropped H1 out of observing for 2 minutes after Guardian brought everything back. This strangely happened twice more before I decided to take SQZ_MANAGER to DOWN to try and reset things, and after doing that and bringing it back to FREQ_DEP_SQZ, things seem okay now.
