Hi All,
Cryo is trouble shooting the high return pressure on the 4K return.
It appears that the T2 bypass valve is not fully seating.
They may decided sometime in the next few hours to do something that could
trip the T2.
All magnets in Halls A and C are now at 0 current as well as the Hall  B
solenoid. 
The Torus is ramping down and should be complete down with an hour. 
Please do not ramp back up until after cryo gives the go ahead.

Dave
