We found the bottom center viewport on HAM4 South door to be leaking at around 2-3 x 10-2 torr*L/sec! -> Tomorrow we will attempt to avoid this leak and resume leak hunting

All annulus volumes in the Vertex, YBM and XBM had been evacuated before helium leak testing began this afternoon.  GV1 was closed then opened and GV2 was closed to demonstrate that the leak was on the Vertex volume and not the YBM or XBM volumes.
