Introduction

A geomagnetic storm refers to disturbances of the Earth’s magnetosphere, caused by sudden strong variations in the speed, density and magnetic properties of the solar wind.

The resulting magnetic field variations within the magnetosphere generate electric currents in long conductors such as power lines and pipelines. The effects of geomagnetic storms range from mild (interference with aeromagnetic surveys) to extreme (electric power grids may experience blackouts or collapse).

This collection compiles resources on geomagnetic storms and space weather.
