Lock loss at about 9:30UTC, and while nothing is broken, many small issues to relaocking.
Bottom Line - I can see the useism effecting the locks; arms in green, arms in red, PRMI, and DRMI, and that's made relocking twitchy.
Details:
- 3 or more times, I had the the PRMI locked and aligned, and when I brought SRM back in, it didn't just break the PRMI, the SRM watchdog tripped
- at least two times, HAM5 ISI also tripped
- during one of those, the BSC2 ISI tripped
- at least 3 times the DRMI locked but not good enough for WFS, and broke before I could manually fix it
- once DRMI locked and WFS did engage, I let it sit for a while, as I took a much needed break, if you must know, and even then it broke on it's way to Engage ASC
- DRMI just relocked and at 11:21UTC, it looks like the IFO might make it back to Low Noise
- at 11:25UTC, IFO is in Engage ASC and looks OK
BSC chambers switched to Quiet90 ISI Blend Filters, and I accepted changes in SDF in order to return to Observe - screen shots attached.
9:31:32UTC - Lock loss, I haven't investigated
11:39:43UTC - IFO returned to Observe
