Aphelion SSW scenario. Upper panels show a cross-section in the meridian plane (at Y = 0 km), while lower panels show a cross-section along the magnetic equatorial plane (at Z = 484 km). Each row shows the maps of the magnetic-field intensity, B, the current components (J_Z in upper panel and J_Y in lower panel), and the particle density. The dotted black lines represent the predicted magnetopause and bow shock’s shapes based on the model proposed in Winslow et al. (2013). The Sun is ideally located on the right edge, and the solar wind flows from the right edge to left.
