Definitions for "Anthelion"
A halo opposite the sun, consisting of a colored ring or rings around the shadow of the spectator's own head, as projected on a cloud or on an opposite fog bank.
luminous white spot that appears on the parhelic circle 180° in azimuth away from the sun. The origin of anthelion is not settled. The brightness of this spot may be due partly to the superposition of the parhelic circle and of the anthelic arcs, which intersect the parhelic circle at this point. Other candidate mechanisms giving light to anthelion have been suggested.
Meteoroids striking the Earth from a direction opposite the Sun. (For example, if the Sun is just rising above the eastern horizon, the "anthelion point" would lie on the other side of the sky, just below the western horizon.)
