While trouble shooting the septum nitrogen level we didn't notice that the global valve for the hall A nitrogen flow went closed again (see picture of HRS LN2 levels)...
We called the cryo tech, he opened the valve again and set the minimum value to 20% so that it won't close again.
Waiting for magnets to fill up ....
