On site making various checks 
Chandra R. has been notified that I am here.  I expect to be here < 2 hrs. doing various checks of the purge-air supplies at the end stations and the corner station, NEG bake in LVEA, VBO C in VPW and CP4 bake in the Y-mid VEA.  

I'll make a comment to this entry when I leave.

Turned off YBM MTP controller and GV5 AIP controller.  Kobelco oil temp running a little warmer than previous 6 months at 105F.  Found flange bolt within Kobelco has worked its way loose and has fallen out.  Flange in question is too hot to work on while running but this can be dealt with on a maintenance day.  Moved RGA laptop from CP4 at Y-mid to VBOC in VPW (we need to install RGA software on a second laptop at some point).  Also, I isolated the scroll pump from Turbo at CP4 and used room air to purge scroll stages of any forming water condensate before restoring to as found configuration.  

During this visit, I started the last 90 minute activation of the final NEG pump on the OMC tube as part of the particulate mitigation exercise.  As such, I'll be able to vent this NEG and do the last UHP N2 blow out anytime tomorrow and be done with this extra step applied to the three vertically oriented NEG pumps.  

1955 hrs. local -> Leaving site now.
