(a) The original flux rope when emergence is stopped at t = 86. This figure is also available as an mpeg animation. (b–d) Three views of the eruption end state at t = 106: two flux ropes separated by cusped loops. The lower boundary shows radial magnetic field strength (red, positive; blue, negative). We refer to the lower boundary of the original flux rope as the rope bipole (red and blue circular poles), and that of the originally potential arcade as the arcade boundary (horizontal red and blue bands). The pink field lines rooted in the rope bipole represent the lower, surviving rope and show the bald‐patch separatrix surface (BPSS). The red field lines rooted in the rope bipole are dipped field lines within the lower, surviving rope that intersect the X = 0, Z = 0 vertical axis. The orange and yellow lines are nondipped but non‐escaping field lines that intersect the vertical axis just above the red dipped lines. The black line is a non‐escaping field line rooted in the arcade boundary, and the purple field line in (b) represents the upper, escaping flux rope rooted in the arcade boundary. The red, orange, yellow, black, and purple lines intersect the vertical axis at evenly spaced intervals.
