We had highly rung up violing modes tonight, in particular 508.289Hz was outrageous.
Nominally it should be on ETMY. We pushed on that optic in pitch, yaw, length, and with all sorts of different filters (narrow ones, broad ones, different feed-back phases, etc.)
We succeeded in ringing up all three neighbouring modes, and thendam them again. But 508.289 never changed its size. We even tried pushing ETMX (its modes are closest to ETMY), but no success...

(There was a typo in the frequency in the first version, hence Evans comment)
