It was very sudden. There was no indication form any of the FOMs that anything was, and the environment looks good. There may be the smallest bump on the BLRMS, but nothing that ever should have dropped it. SR3 lockloss template attached, doesn't seem to be the cause (I zoomed in this time unlike before). Also attached the generic lockloss plots, which I can't tell if any of it is out of the norm. Myabe MICH was a bit more active a few seconds before it dropped, but it does sometimes seem to do that normally.
IMC is having trouble staying locked, I should stop writing here and get back to that.
