[Steve, Manasa]

I checked the alignment one last time. The arms locked, PRM aligned, oplevs centered.

We went ahead and put the heavy doors ON. Steve is pumping down now!

 The ion pumps were vented just before pumpdown and their gate valves were opened.

This is an effort to minimize a possible leak through their gates.

Is there a volunteer who goes home late and would close off the roughing? tonight
