Lockloss @ 02/18 00:06 UTC after almost 5.5 hours locked
This lockloss also has the strange oscillation in many LSC channels + QUADs right before the lockloss that was noted in 82847
03:05 UTC OBSERVING
Looking at front room ndscopes+QUADs/DARM in the minute leading up to LL: ndscope1
Oscillation seen by QUADS, ASC-INP1_P_IN, and ASC-CHARD_P_OUT
NOT seen in power recycling gain or circulating power (like the LL that happens after this one - 82865)
Looking at QUADS/DARM and LSC signals in the second before the LL: ndscope2
Seen by all QUADS, DARM, and LSC signals
