The white spot on the lower left part of the parhelic circle, opposite to the sun, should be an anthelion, a bright halo always located at the antisolar point. |
Anthelio derives its name from anthelion, the halo around bodies directly opposite the sun. |
Incidentally, it is widely believed that the anthelion is the origin of the tradition of painting a halo around the head of saints in Western art. |
The anthelion is a spot on the parhelic circle, where the Wegener arcs, the Hastings arcs and the Tricker arcs cross the parhelic circle and increase the brightness. |
According to this theory, the anthelion should be visible together with other halos caused by column-shaped crystals if the ice crystals are spread over the whole sky. |
Finally, the minor, slightly bluish dots, flanking the anthelion, may be perfectly depicted 120° parhelia. |
