Once the wind died down I was able to run an initial alignment skipping green arms. This ran without issue. I then tried to lock PRMI and had to move PRM and BS a fair amount to get it to lock.  DRMI then locked with only a little bit of SRM movement. There was a ~0.5Hz oscillation seen in MICH before we got to engaging ASC for full IFO, but the ASC seemed to calm this down. Smooth sailing after that to low noise.

Our low frequency noise is still not great, putting our range at 140Mpc. I was warned of this and since LLO and Virgo were down I also ran a SQZ scan to maybe help, but its not that easy.

There are P2L and Y2L SDF diffs attached. I don't see any A2L mentions in todays alog, only from yesterday.
