OPS Thursday DAY shift start
TITLE: 12/12 Day Shift: 1530-0030 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Observing at 153Mpc
OUTGOING OPERATOR: TJ
CURRENT ENVIRONMENT:
SEI_ENV state: CALM
Wind: 8mph Gusts, 4mph 3min avg
Primary useism: 0.03 μm/s
Secondary useism: 0.32 μm/s
QUICK SUMMARY:
- We've been locked for 10 hours, range looks lower than the start of the lock
- 2ndary microseism is trending up again
- Low wind
- Comissioning plans are from 9-12 PST, 17-20 UTC, calibration measurement at 16:30
- I power cycled the dust monitor in the vac prep lab but it still shows as disconnected
I ran the coherence check and range comparison (Sheila said she's not sure if these plots are showing exactly what they should be though) comparing the better range at the start to now.
2ndary microseism also took a step up above the 90th percentile in the past 30 minutes and brough SEI_ENV to useism.
