Anaurora (plural: aurorae or auroras; frae theLaitin wirdaurora, "sunrise" or the Roman goddess o dawn) is a naitural licht display in the sky pairticularly in the heich latitude (Arctic anAntarctic) regions, caused bi the collision o energetic charged pairticles wi atoms in the heich altitude atmosphere (thermosphere). The charged pairticles oreeginate in themagnetosphere ansolar wind an, on Yird, are directit bi theYird's magnetic field intae the atmosphere. Maist aurorae occur in a band kent as theauroral zone,[1][2] which is typically in 3° tae 6° latitudinal extent ogeographical poles, or equivalently, 10° tae 20° latitudinal extent ogeomagnetic poles, an at aw local times or longitudes. During ageomagnetic storm, the auroral zone expands tae lawer latitudes.
