Ops DAY Shift Start
TITLE: 11/17 Day Shift: 16:00-00:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Observing at 155Mpc
OUTGOING OPERATOR: Austin
CURRENT ENVIRONMENT:
SEI_ENV state: CALM
Wind: 4mph Gusts, 2mph 5min avg
Primary useism: 0.01 μm/s
Secondary useism: 0.17 μm/s
QUICK SUMMARY:
Detector in Observing and Locked for 4.5 hours. Looks like this last lockloss was from an earthquake.
The lockloss from last night 11/17 08:32UTC was definitely from an earthquake(EQResponse, Peakmon/LSC, SeismicFOM).
The detector correctly waited for the ground and oplevs to settle, and afterwards locked itself without any input and did not even go through Increase Flashes or an Initial Alignment.
