The authors address the question of the origin and meaning of the Harang discontinuity. They consider mappings of the ionosphere, auroral zones, and magnetosphere. They argue for a relation between the velocity shear zone in the auroral ionosphere and the Harang discontinuity. However because of the upward directed field-aligned currents it is very hard to trace field lines well enough to show mappings of these zones. They argue however for the behavior of auroral arcs in relation to the appearance of substorm events to provide strong support for this relationship.
