Zoomed-in details of the wave front interaction with the remote flux rope, focused on the X-point below the prominence hosting flux rope. The temporal evolution of the current density, |j_z|, is shown normalized to the instantaneous maximum value in the region, |j_z|_max, along with the magnetic field lines at the bottom of the flux rope after its interaction with the primary front. The white lines in each panel denote the instantaneous position of the same magnetic field lines. Animation 5 shows the temporal evolution in the time interval 28.6 − 50.1 minutes. An animation of this figure is available online.
