OPS OWL Mid-Shift Update
  1. Lockloss at 8:41 UTC for unknown reasons (DRMI unlocked, though not much ground motion or wind).
  2. Lock 1: It was a fully automated lock and until violin damping, was the most stable/easiest one I’ve seen yet! It would’ve been a sub-40 minute lock if not for IY Violin modes.
    1. Increase flashes for both ALS X and Y.
    2. DRMI Locked without going to PRMI
    3. Reached OMC_Whitening (state before NLN) at 9:34 UTC but it took an additional 37 minutes of just damping IY modes since those were heavily rung-up. Didn’t touch anything though since they were all going down as expected.
    4. Reached NLN at 10:11 UTC.
  3. Other: DARM FOM crashed when we lost lock and since restarting, it is glitching every so often.

IFO STATUS: IFO is at NLN and in OBSERVING as of 10:13 UTC
