Lockloss 19:02 UTC
Unknown cause Lockloss. Sheila and I were troubleshooting a host of SQZ mysteries when this happened (not actually touching anything just discussing). It's tempting to say SQZ related since all our issues this weekend have been but yet unknown.
Back to NLN as of 20:31 UTC
Sheila and I troubleshot more SQZ stuff, ultimately deciding to turn off SQZ ANG ADJUST since it was oscillating the phase, and thus our range, unnecessarily. I edited sqzparams.py to turn it off and then had to edit SQZ ANG guardian to make DOWN the nominal state. Now we're observing but will need to manually change the angle to optimize range, which I just did and will do again once thermalized.
