I'm not fully sure that it's meaningful, and I've let Betsy and TJ know since they're doing a deeper dive into our temperatures and suspensions, but it seems that today (~5 hours ago, while we were unlocked) we had more motion around the microseism for several of our optics, including all 4 quads for some of their top mass degrees of freedom. However, the BLRMS of our microseism don't seem to have increased by the ~order of magnitude that some of these suspension degrees of freedom seem to have moved. I don't have any evidence that this is related to our locking difficulties, but it seemed worth writing down.
Arnaud just pointed out to me that several of the oplevs on the summary page (including SR3 and ITMX, for example) all see this increased motion, and it was for a finite duration of time. So, probably unrelated to our locking difficulties, and just a result of temporary excess ground motion (perhaps the road construction, as TJ conjectured?). EDIT: Arnaud again to the rescue, it's not motion seen in the ground seismometers (which is consistent with the lack of elevated motion in the BLRMS). So, some other maintenance-related activity.
So, my plots of elevated motion are just a case of a poorly chosen time of day (I was looking for a time when we were DOWN, to make an easier-to-interpret set of plots to check for rubbing). Thanks Arnaud!
