作者解决的问题的起源和意义的哈朗不连续。他们考虑电离层，极光区和磁层的映射。他们认为极光电离层中的速度剪切带和哈朗不连续之间的关系。然而，由于向上定向的场向电流，很难很好地追踪场线以显示这些区域的映射。然而，他们认为极光弧的行为与亚暴事件的出现有关，为这种关系提供了强有力的支持。
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.
