Ops Day Shift Start

TITLE: 08/20 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Observing at 152Mpc
OUTGOING OPERATOR: Ryan S
CURRENT ENVIRONMENT:
    SEI_ENV state: CALM
    Wind: 3mph Gusts, 1mph 3min avg
    Primary useism: 0.01 μm/s
    Secondary useism: 0.07 μm/s
QUICK SUMMARY: Locked for 11.5 hours, no alarms, calm environment. Looks like we dropped Observing at 1053-1057UTC because the SQZr lost lock and relocked.

Our range isn't as stable as it has been lately, and the Omicron glitch gram FOM shows some extra SNR around 20-30Hz during those times.
