This morning, the SUS crew added the remaining mass to the H2 ITMY QUAD structure by adding the stiffening sleeve with vibration absorbers.  The seismic crew has now balanced the ISI with the full ITMY and FMY structures.  The BSC-ISI is now locked so that Romer arm measurements can begin on the ITMY QUAD and Test Mass. The afternoon's goal is to have the BSC-ISI floating with the H2 ITMY fully suspended and OSEM flags to center-range.
