Horizontal slice through the simulation showing ȷ_z at t = 11 360 s and at a height of 4 Mm in 2D (top-left) and 3D (top-right and bottom panels). The component ȷ_z shows multiple QSLs that are associated with the magnetic features responsible for reconnection. The lower oval-shaped QSL is associated with a horizontal flux rope, as denoted with an arrow on the top-left panel and illustrated with red lines in the bottom-left panel. The upper oval-shaped QSL is associated with a magnetic arcade as denoted with an arrow in the top-left panel and illustrated with cyan lines in the bottom-right panel. The intersection between these features is located at the intersection between the two QSLs, as denoted with an arrow in the top-left panel.
