Wed EVE Ops Transition
TITLE: 05/08 Eve Shift: 2300-0800 UTC (1600-0100 PST), all times posted in UTC
STATE of H1: Lock Acquisition
OUTGOING OPERATOR: TJ
CURRENT ENVIRONMENT:
SEI_ENV state: CALM
Wind: 17mph Gusts, 12mph 5min avg
Primary useism: 0.04 μm/s
Secondary useism: 0.16 μm/s
QUICK SUMMARY:
H1 just had a lockloss as I arrived and Sheila/TJ were investigating alignment into/around the OFI. Winds are lighter than yesterday thus far. Microseism also turned down from the step up 24hrs ago (now hovering just above the 50th percentile).
22:48 UTC Lockloss. There was a 5-6 Hz oscillation in DARM and a little wiggle 10 ms before the lockloss.
