Ops Day Shift Start
TITLE: 09/24 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Observing at 153Mpc
OUTGOING OPERATOR: Tony
CURRENT ENVIRONMENT:
SEI_ENV state: CALM
Wind: 2mph Gusts, 0mph 3min avg
Primary useism: 0.01 μm/s
Secondary useism: 0.14 μm/s
QUICK SUMMARY: H1 has been locked for 3.5 hours. One lockloss overnight with an unknown cause, but relocking seems to have gone without issue. We will have a short planned commissioning window from 16:00 to 17:00 UTC.
- Wind and other ground motion low
- All other systems nominal
The hour of commissioning time did not happen today due to calibration report issues at LLO. This has been added onto tomorrow's regularly scheduled commissioning time, so we will have a total of 4.5 hours (with the first 30 minutes dedicated to calibration sweeps, as usual).
