QUICK SUMMARY:
After manual Initial_Alignment
We tried to get locked but there were issuses getting DRMI 1F and then PRMI.
I then touched the Beam Splitter and SRM a little bit to try and get PRMI locked with no luck.
I then took IFO to Check mitch fringes. Where it struggled some more to get past PRMI.
I then Took the IFO to Initial Alignment.
After Initial_Alignment H1 was able to get past DRMI locking and got to Nominal_Low_Noise.
Nominal_Low_Noise @ 1:31 UTC
SQZrs were touching up SQZ alignment and to get the SQZ system locked. https://alog.ligo-wa.caltech.edu/aLOG/index.php?callRep=77400
