OPS Friday day shift start
TITLE: 12/08 Day Shift: 16:00-00:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Observing at 156Mpc
OUTGOING OPERATOR: Austin
CURRENT ENVIRONMENT:
SEI_ENV state: SEISMON_ALERT
Wind: 9mph Gusts, 8mph 5min avg
Primary useism: 0.06 μm/s
Secondary useism: 0.58 μm/s
QUICK SUMMARY:
- We've been locked for 13:20, in observing since 02:37UTC
- CDS reports 12 channels not connecting, they're all MONITOR_NUC26 channels
- Microseism still higher than usual
- ITMY modes 5/6 and 8 are decently high, ~4.5 on the VIOLIN_MONITOR medm, I'll work to damp these down
nuc26 (upper camera-fom machine) froze up at 22:54 Thu 07dec2023 PST, resulting in an EDC disconnected chan count of 12. TJ rebooted this machine and all is good now.
ITMY mode8 is damping down very nicely with FM1+FM5+FM10 G=+0.3 but for ITMY modes 5/6, 6 is damping but 5 seems to be slowly rising using FM6+FM8+FM10 G= -0.01 based on the narrow and broad monitors, but on DTT they both appear to be rising.
