5. a. A luminous atmospheric phenomenon, now considered to be of electrical character, occurring in the vicinity of, or radiating from, the earth's northern or southern magnetic pole, and visible from time to time by night over more or less of the adjoining hemisphere, or even of the earth's surface generally; popularly called the Northern (or Southern) Lights, merry-dancers, streamers, etc.
The northern lights, being alone conspicuous in Europe, had from the earliest periods various popular names in the northern languages; they began to attract scientific attention early in the 17th c., and were described by Gassendi in 1621 (see quot. 1822) under the descriptive appellation of aurora borealis or ‘northern dawn,’ their simplest form suggesting the appearance of dawn or approaching sunrise on the northern horizon; this appellation (occasionally varied as aurora septentrionalis) passed into general scientific use. On the recognition of similar phenomena in the antarctic regions, these were called aurora australis or ‘southern lights’; whence aurora is now used generically as the proper term for the phenomenon, without any thought of ‘dawn,’ and with English plural auroras; and this has become the ordinary prose meaning of aurora, the preceding senses being only poetical.
