Overlying reconnection at t = 137. The colour scheme is as before. Reconnection no longer takes place at a single point but at several throughout the current sheet, as indicated by the box that covers the whole of the top of the EFR. A map of B_z is displayed at the base of the photosphere (z = 0). The reconnected field lines now connect inside the footpoints rather than at the edges. The ambient field has been omitted for clarity.
