DQ Shift LHO 03 Feb- 09 Feb 2025
Summary: Average duty cycle for LHO this week was 65.4% The BNS range fluctuated between 140 and 160Mpc this week A couple of the locklosses can be explained due to ground motion Friday's earthquake at 04:51 UTC Saturday's earthquake at 23:31 UTC, which extended to sunday morning Multiple Superevents this week! Strange noise pattern in H1 BSC2 motion Y Wednesday through Sunday Fscan line count was very low on Saturday and Sunday (below 600) Multiple new channels in Hveto this week Full report: https://wiki.ligo.org/DetChar/DataQuality/DQShiftLHO20250203
Yashasvininad interestingly pointed out some BSC2 (BS chamber) Accelerometer motion wandering at 5-10Hz that started around Feb 3rd-Feb 4th /summary/day/20250204/pem/accelerometers_corner_bscs/ and we still have. I cannot see it before Feb. It's very visible in the last two days. e.g. plot.
