The Liljequist parhelion is a type of atmospheric optical phenomenon associated with the appearance of bright spots (parhelia) that are seen on either side of the Sun. It belongs to a category of halos and is specifically formed by the refraction and reflection of sunlight by ice crystals suspended in the atmosphere, typically in cirrus or cirrostratus clouds.
