Took H1 to DC Readout for Kiwamu to run high power tests.
Toward the end of the shift, H1 could not lock the OMC. Kiwamu traced this down to a rung up violin mode for ETMy. I remember watching others damp violin modes, but I have not done it before. I tried looking through wikis and alogs for instructions but could not find any.
H1 taken to a DOWN state for the night.
