A na-arụ ụka banyéré otú e si emepụta anthelia. Walter Tape, n'etiti ndị ọzọ, ekwuola na ha abụghị haloes dị íchè íchè, kama ọ bụ naanị ébé haloes dịgasị iche iche nke kristal ice dị ka ogidi na-adaba na gbụrụ-gbúrụ parhelic iji mepụta ntụpọ na-egbuke egbuke. Ọ bụrụ na echiche a ziri ezi, anthelia ga-apụta naanị na haloes ndị ọzọ a.^[1]

Otú ọ dị, anthelia na-apụta na-enweghị haloes crystal ndị ọzọ, ya mèrè ndị ọkà mmụta sayensị emeela nkọwa ndị ọzọ. Prọfesọ Dutch S.W. Visser tụrụ aro na ha na-emepụta site na ngosipụta ọkụ abụọ dị n'èzí na prisms quadrangular, ébé Robert Greenler tụrụ aro ngosipụta abụọ dị n"ime na kristal ndị dị ka kọlụm na-emepụta ihe omume ahụ.^[1]

Ọ bụ ezie na ebe anthelion na-adịkarị obere na haloes, na ngosipụta dị mgbagwoju ányà ọ na-egosipụta ihe ọhụụ dị ichè ichè a na-adịghị ahụkebe: Flanking the anthelion on the parhelic circle is two 120 ° parhelia (and two Liljequist parhelia) caused by plate crystals. A na-emepụta oghere ndị aghụghọ na ndị na-agbasa agbasa n'otu oghere ogidi ma mepụta ọdịdị ankh nké na-agafe anthelion. Wegener arcs na-agafe igwe mgbé ụfọdụ iji gbakọta na anthelion.^[2]
