Term: SubAuroralRegion
Definition:

When considering the case of the Earth, thesub-auroral region typically refers to two latitudinal bands, one in thenorthern hemisphere and the other in the southern hemisphere extending fromabout 50 degrees to low 60 degrees. The concept sub-auroral regions does notapply to all bodies in the solar system and different latitudinal rangeswould apply for each body case by case. The sub-auroral regions may bedefined by using either planetographic or magnetic coordinates if themagnetic dipole is closely aligned with the spin axis of a magnetized body.Ground magnetometers located at sub-auroral latitudes on the Earth measure amixture of activity driven by auroral zone currents and the ring current.
