ITMY optical lever noisy
the ITMY optical lever is noisy (screenshot attached). It would be a good idea to check for mechanical interferences when there is an oppurtunity.

I did a walkthrough and a visual did not reveal any obvious mechanical coupling. Both piers were as isolated as usual. Spectrograms were examined and besides optical motion there was no broadband glitching evident. We'll keep an eye on this.
