Plots look like there was possibly some movement of ASC-C soft before the actual lockloss.

While I did have two 4.5M Earthquakes enroute to pass through at the time, the ground motion was fairly low right as the lockloss happened. It's been quite a night of earthquakes so I had all the ground motion plots up and have been watching them like a hawk.

The PI plots look wild to me with the plateau on PImode 28 and 29 , so I took a pic of the log on SUS_PI .

There may be a smoking gun in there somewhere, but the PI's seem within what I recall being healthy bounds.

So cause is still unknown.
