Ops Day Shift Start
TITLE: 04/24 Day Shift: 15:00-23:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Lock Acquisition
CURRENT ENVIRONMENT:
SEI_ENV state: CALM
Wind: 0mph Gusts, 0mph 5min avg
Primary useism: 0.01 μm/s
Secondary useism: 0.08 μm/s
QUICK SUMMARY: Still locked but with a range around 120Mpc. Lots of noise in almost the entire of the spectrum.
TJ took no SQZ time this morning from 15:31:30 to 15:45:00UTC. Plot attached comaping now to no SQZ time from April 12th 77133
TJ and I looked at the OFI (plot) and over the last 5 days, the RT voltmons has changed more than usual. We aren't actively damping the OFI though so are unsure if these VOLTMONs are just reading noise...
We checked the HWS _PROBE_TOTAL_PIXEL_VALUE and the position of IFO beam on IX and IY HWS, from last good long range power up 2024/04/21 20:55UTC (1397768177) to last nights power up 2024-04-24 07:26UTC (1397978835). No difference in the two times seen. HWS cares about SR3.
