             abstract = "We present predictions for the evolution of FTEs generated by 
                         localized bursts of reconnection on a planar magnetopause that 
                         separates a magnetosheath region of high densities and weak 
                         magnetic field from a magnetospheric region of low densities and 
                         strong magnetic field. The magnetic fields present a shear angle 
                         of 105 degrees. Reconnection forms a pair of FTEs each crossing 
                         the magnetopause in the field reversal region and bulging into the 
                         magnetosphere and magnetosheath. At their initial stage they can 
                         be characterized as flux tubes since the newly reconnected 
                         magnetic field lines are not twisted. Reconnection launches 
                         Alfvenic perturbations that propagate along the FTEs generating 
                         high-speed jets, which move the pair of FTEs in opposite 
                         directions. As the FTE moves, it displaces the ambient magnetic 
                         field and plasma producing bipolar magnetic field and plasma 
                         velocity signatures normal to the nominal magnetopause in the 
                         regions surrounding the FTE. The combination of the ambient plasma 
                         with the FTE flows generates a vortical velocity pattern around 
                         the reconnected field lines. During its evolution the FTE evolves 
                         to a flux rope configuration due to the twist of the magnetic 
                         field lines. The alfvenic perturbations propagate faster along the 
                         part of the FTE bulging into the magnetosphere than in the 
                         magnetosheath, and due to the differences between the plasma and 
                         magnetic field properties the perturbations have slightly 
                         different signatures in the two regions. As a consequence, the 
                         FTEs have different signatures depending on whether the satellite 
                         encounters the part bulging into the magnetosphere or into the 
                         magnetosheath. Key Points Vortical flow associated to FTEs Single
