SAR sta per “Stable Auroral Red arches“, archi rossi aurorali stabili. È un nome tremendo, perché non sono né aurore (come detto) né stabili (variano nel giro di minuti), ma quando la nomenclatura fu introdotta nel 1956 non si sapeva nulla di tutto questo. Sono di colore rosso per lo stesso motivo dell’aurora: eccitazione di ossigeno monoatomico ad altissima quota (300-600 km). Tuttavia il meccanismo di generazione è totalmente diverso.
I SAR infatti non sono prodotti dal vento solare, ma in un certo senso dalla Terra stessa! Quando si scatenano tendono a interessare le latitudini medie (cioè l’Europa mediterranea). La loro origine sta nelle famose fasce di Van Allen, due vaste cinture di radiazioni che circondano la Terra. Al loro interno il campo magnetico terrestre confina le particelle in arrivo dal Sole. La fascia più interna è fatta principalmente da protoni ed elettroni lenti, la più esterna da elettroni veloci.
