Got called at 4:50 due to a mysterious SRM trip at 4:47 AM. IFO was in SRC ALIGN for initial alignment and SRM was railing during PREP_FOR_SRY. ST2 and ST3 sus tripped, which makes me think that initial alignment may have caused it? Microseism is on the rise but nothing jumps at me otherwise (attached).
Either way, I untripped it and waited until IFO got to DRMI which it just did. Flashes look good. Will continue light monitoring but I think guardia can take it from here.
Reset myself as the OWL.
Taking a look at some of the signals, SRM tripped at 11:47:36, about 30 seconds after it was aligned. An oscillation started ~5 seconds before the WD trip. ALIGN_IFO was starting SRC, the motion was mostly seen by the lower stage osems, M1 did not trip (barely, LF and RT saw an RMS of 140 where the trip threshold is 150). LF and RT seemed to see the largest motion, DAMP_Y_INMON was much larger than P which also tracks with that.
