2025 April vent - VAC diary
Today's activities:

- All the turbos have been valved out and switched off
- The corner was vented through the Y-manifold vent valve, with 3-4 Torr/min speed - it took 3.5 hrs
- As a side effect, the current of GV5's AIP went up, so now this Annulus volume is being pumped with an aux cart
- Another aux cart is pumping the RGA in the corner (between HAM5 and HAM4)
