~1020 hrs. local -> Started test running of pumps on LVEA floor @ BSC8

(see WP6332)

Also running turbo pump connected to PT180 hardware on dome of BSC8.  Coordinating with PEM folks to see if the IFO commissioning community can live with this noise source for a few days.  If so, we (Vacuum) would then bake the PT180 hardware while being valved-out from the YBM and while being pumped by these temporary pumps.  

Will be leaving these run past the official "Maintenance Day" period so as to see what these look like if/when the IFO is in low-noise.  May need to do some "on/off" tests as per Robert S.
