The 200lbs mass stack used to account for the missing PR3 apreared to be causing unwated resonances around 113Hz. We could hear the bottom mass tilting against the optical table when being hit. We untorqued the stack and put a folded alluminium strip under its problematic corner. Everything is torqued down. We cannot hear the mass rocking anymore.

2 potentially rubbing cables were found on the North and South sides. They were adjusted.

HAM2-ISI is locked so suspensions can be adjusted in pitch. It will be unlocked to pursue testing afterwards.
