Lock Loss 19:48

Since the initial alignment hasn't been done since last night. I'm redoing the initial alignment. Wind speed looks good so hopefully I can get it back up again soon.

20:40 PSL untripped but having trouble locking IMC. I cleared all the IMC WFS history but that didn't help. Still working on it.

22:18 Locking again on LOWNOISE_ESD_ETMY at ~11 Mpc. I had to tweak all the IMC optics to get IMC to lock again after PSL tripped. Intent bit switched to Undisturbed at 22:28.
