Ops Day Shift Start
TITLE: 02/10 Day Shift: 1530-0030 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Aligning
OUTGOING OPERATOR: Ryan S
CURRENT ENVIRONMENT:
SEI_ENV state: CALM
Wind: 11mph Gusts, 6mph 3min avg
Primary useism: 0.02 μm/s
Secondary useism: 0.32 μm/s
QUICK SUMMARY: Recent lock loss, IFO just finished up an initial alignment. Planned commissioning today from 1630-1930 UTC.
There was a vacstat alarm this morning, attached is the blip it alarmed off of. The height of this peak seems fairly normal when trending back, happening once every few days or so. It also doesn't coincide with a lock loss, we were in low noise during this time.
We had a BSC3 gauge glitch at 00:59:17 which caused the VACSTAT alarm. I have restarted the service to clear it.
