H1 Back to Observing

H1 is back to observing as of 00:55 UTC after a day of commissioning and a lockloss late this afternoon.

After running an alignment, DRMI locked easily, but DRMI ASC pulled things away from good alignment and there was a lockloss during DHARD_WFS. The next attempt needed a run through PRMI, which caught and PRMI ASC worked well. No other issues during the locking process. The only SDF diff I needed to address was the SQZT0 picomotor driver was left on (and is now off).
