Comment to ETMY alignment, one day after pumping down using oplev (4025)

Still a lot of excitation can been seen. They are roughly once per 10 minutes.

I hear the current pressure is already 1e-4Pa. It is not easy to think that excitations happen due to the pumping down in such a high vacuum.

Hitting somewhere?
