4 definitions found From Webster's Revised Unabridged Dictionary (1913) [web1913]: Aurora \Au*ro"ra\, n.; pl E. {Auroras}, L. (rarely used) {Auror[ae]}. [L. aurora, for ausosa akin to Gr ?, ?, dawn, Skr. ushas, and E. east.] 1. The rising light of the morning; the dawn of day the redness of the sky just before the sun rises. 2. The rise, dawn, or beginning. --Hawthorne. 3. (Class. Myth.) The Roman personification of the dawn of day the goddess of the morning. The poets represented her a rising out of the ocean, in a chariot, with rosy fingers dropping gentle dew. 4. (Bot.) A species of crowfoot. --Johnson. 5. The aurora borealis or aurora australis (northern or southern lights). {Aurora borealis}, i. e., northern daybreak; popularly called northern lights. A luminous meteoric phenomenon, visible only at night, and supposed to be of electrical origin. This species of light usually appears in streams, ascending toward the zenith from a dusky line or bank, a few degrees above the northern horizon; when reaching south beyond the zenith, it forms what is called the corona, about a spot in the heavens toward which the dipping needle points. Occasionally the aurora appears as an arch of light across the heavens from east to west. Sometimes it assumes a wavy appearance, and the streams of light are then called merry dancers. They assume a variety of colors, from a pale red or yellow to a deep red or blood color. The {Aurora australis}is a corresponding phenomenon in the southern hemisphere, the streams of light ascending in the same manner from near the southern horizon.
