Lockloss @ 3:43 UTC

LOCKLOSS @ 3:43, this one might be from the EQ. Interestingly enough, SEI_CONF went to CALM (it went to the EQ state, but there was no indicator on Verbal that it ever transitioned in the first place?), and we lost lock shortly after. Notice right after the lockloss the MC_TRANS camera was moving quite significantly in pitch, more evidence that this was potentially motion related.

However, the peakmon ndscope was showing very little movement (~100 counts at the time of the lockloss - scope attached), also the BLRMS for the EQ band was at or right below 0.1 um/s. This is pretty contradictiory, I'm wondering if this was just a coincidence and not EQ related at all? Tagging SEI

EDIT: The lockloss tool did not tag any ground motion related tags, and the lockloss select tool is not showing any ASC/LSC ringups from my eye, conclusion: inconclusive.
