Hevelius's parhelia
Hevelius's parhelia
[he′vel·yəs·əz pär′hēl·yə] (optics)
Bright spots infrequently observed on the parhelic circle halfway around from the sun to the anthelion; these two brighter areas on the parhelic circle are probably a result of superposition of luminosity of the parhelic circle and the Hevelian halo.
