Recieved a call at 10:38UTC regarding the detector having issues relocking. It was stuck in an Initial Alignment at Green Arms, and right when it started the initial alignment, almost every suspension saturated, including the RMs and SQZ suspensions. We were also getting constant IFO OUT and MC2 saturations while in green arms. At 10:39UTC the ISI BS Stage 2 WD had tripped after many BS saturations.
We also have multiple large earthquakes coming in from the Phillipines and so the first thing I did was take the detector to DOWN. The R-waves of the earthquakes are now hitting us, and ITMY Stages 1 and 2 WDs have also tripped due to a very sudden and large spike in ground motion. At 11:36 everything is calmer in the chambers so I reset the watchdogs on both ITMY stages and BS stage 2.
13:23UTC Ground motion has calmed down enough that we can start relocking. Starting an Initial Alignment.
13:23UTC Started an Initial Alignment
I was getting the same issue as I had last time - once we get to ACQUIRE_XARM_IR, we aren't able to lock the XARM in IR, and just get a lot of MC2 and IFO_OUT saturations, and the IMC keeps unlocking.
I was going to try running the dark offsets script since that is what worked(ish) for Jenne and Ibrahim (74472), but partway into setting that up (I haven't run one yet and was going to go off of 69650), I decided (also with previous permission from TJ) that the best thing to do would just be to put the detector in DOWN until commissioners can help with relocking during the DAY shift, especially because if the issue is similar to the one I had a few nights ago, I do not know exactly what they did or what to look at. Hopefully relocking in a couple of hours goes well!
