Abstract
GEOMAGNETIC storms fall into two distinct categories: recurrent and sporadic. Recurrent storms are produced by continuous streams of particles issuing from the solar M-regions. Swept round by the rotating Sun, the corpuscular streams overtake the Earth in its orbit at monthly intervals. By contrast, a sporadic magnetic storm marks the arrival of a single cloud of plasma, ejected at the time of a solar flare.
