In this contribution we describe some recent observations of high-speed magnetized flows in the quiet Sun granulation .
These observations were carried out with the Imaging Magnetograph eXperiment ( IMaX ) onboard the stratospheric balloon Sunrise , and possess an unprecedented spatial resolution and temporal cadence .
These flows were identified as highly shifted circular polarization ( Stokes V ) signals .
We estimate the LOS velocity responsible for these shifts to be larger than 6 km s ^ { -1 } , and therefore we refer to them as supersonic magnetic flows .
The average lifetime of the detected events is 81.3 s and they occupy an average area of about 23 000 km ^ { 2 } .
Most of the events occur within granular cells and correspond therefore to upflows .
However some others occur in intergranular lanes or bear no clear relation to the convective velocity pattern .
We analyze a number of representative examples and discuss them in terms of magnetic loops , reconnection events , and convective collapse .
