View of the ecliptic plane as seen from north, showing the results from the shock model in 3D and the magnetic connectivity. For each panel the yellow sphere represents the Sun in true scale, the coloured ellipsoid represents the reconstructed pressure–shock wave with a colour map that corresponds to the different shock parameters, the red and blue lines respectively represent the magnetic field lines connected to STA and STB spacecraft. These hundred connectivity lines are created according to a random number of latitude and longitude taken in a normal distribution around main latitude and longitude. The surface of the pressure–shock wave is coloured according to M_A, V_sh, and θ_BN values in the top, middle, and bottom rows, respectively. From left to right, the panels show the shock position at 07:19, i.e. just before its connection to STA field lines; at 07:28, just before the connection to STB field lines; and at 08:10, when the shock has been connected to both spacecraft (times in UTC).
