When a geomagnetic storm is in progress the auroral ovals, usually located near the Arctic and Antarctic circles, broaden and move out towards the equator. Estimates suggest that a catastrophic event could lead to problems costing between. Geomagnetic latitude, ground conductivity and distance from the coast’s highly conducive seawater can measure the region’s susceptibility to geomagnetic storms. Mekonnen, M. Geomagnetic storm, disturbance of Earth's upper atmosphere brought on by coronal mass ejections—i. 2, 1859, produced intense auroral displays as far south as the tropics. They think it may have been caused by a geomagnetic storm happening for the first time in an area of the Earth’s magnetosphere called the foreshock. There are many lines of evidence to suggest that to first order the near-Earth magnetospheric field, except during some phases of geomagnetic storms and at auroral latitudes, is that of a symmetric ring current aligned with the geomagnetic dipole equator at roughly 3–4 Earth radii (Daglis et al. A geomagnetic storm is a major disturbance of Earth's magnetosphere that occurs when there is a very efficient exchange of energy from the solar wind into the space environment surrounding Earth.
