Lockloss @ 0:42, cause unknown. Not seeing a whole lot of evidence for an ASC ringup. On the LSC side of things, it would seem like LSC DARM IN1 is the first to see the instability followed shortly by the ASC AS A DC PD, scope attached. Looking at the locklost website, it would seem that the ETMX L2 UL/UR OSEM stages are seeing the elevated oscillations ~30 before the lockloss occurred.
