Our optics are moving more than they should be with the ground motion we have right now.  It seems to be sudden glitches, which seem to be impacting mulitple suspensions. 

We can see that if we sit with just the green arms locked ITMY optical lever seems to have 0.5 urad glitches.  ETMY also shows some glitches.  The Y arm ALS control signal also shows these large glitches, and when we lock the interferometer these glitches also show up in IMC F..

Was there some configuration change today that might have caused this? 

It doesn't look like any of our ISI to suspension FF is engaged now.
