OPS Owl Shift Start
TITLE: 06/27 Owl Shift: 07:00-15:00 UTC (00:00-08:00 PST), all times posted in UTC
STATE of H1: Observing at 137Mpc
CURRENT ENVIRONMENT:
SEI_ENV state: CALM
Wind: 6mph Gusts, 4mph 5min avg
Primary useism: 0.01 μm/s
Secondary useism: 0.05 μm/s
QUICK SUMMARY: In NLN for 5h45. ITMY Mode5/6 violins slightly high
Dust monitors, SUS, SEI, CDS, VAC okay. Our DMT online.ligo.org/ "Observe" data isn't updating.
ITMY modes 5/6 damped fine once I engaged the nominal damping settings (IY05 @ -0.04). As the modes were rang up the VIOLIN_DAMPING guardian had set IYmode5 gain to "max_gain" value of 0, we could change this to -0.04 or -0.01, tagging SUS.
