Ops Owl Shift Transition
Relocking is going okay. Stopping at Violin_Mode_Damping_2 to squish one of the fundamental modes that rung up high.
A bunch of ETMX CDS overview went red briefly, middle ish column (either DAC or DAQ). Came with OMC DC PD saturation warning. And the red went away before I could look closer.
Accepted ETM and ITM SDF differences after making sure ETMX bounce mode was not ringing up. The rest are gain settings. Back to Observe.
An accepted PI differences. Had to changes mode 28 filter and PLL set freq. Back to Observe again.
Nutsinee is correct, at the same time we got a SUS-ETMX glitch the OMC PD DC ADC channels saturated. The time was 08:42:49 UTC. The saturations stopped 2 seconds later, the glitch was cleared at 08:44:04 UTC (cronjob running on the minute). Could this be a wierd coincidence?
