Lockloss at 14:18 UTC
Ongoing long recovery from Jim's lockloss (alog 54580).
Not use why all the optics seem so badly aligned. I couldn't get PRMI to lock. It was very off in Pitch but I kept loosing lock adjusting it. Keita by phone helped me get through initial alignment, by aligning BS while watching ASC-AS_A_DC, and at 21:40 we have finally locked DRMI!
Livingston called to say they are down for such a long period due to storms, microseism, wind AND a complete power outage.

- 22:19 NLN (finally!) SDF diifs attached:
- There was lots of small 10-32 ones in CALCS (image) which have bee seen in the last few locks. I accepted.
- There was 2 for ETMY_M0_TEST_OFFSETS, from when I exited out of initial alignment (sorry!). Offsets currently off, so I reverted.
- There are 2 from ALS_Y_WFS I don''t know about. Maybe changed when Jim was troubleshooting, I accepted as it seems like they are still in use (photo). Tagging ISC?!
