Analogous to a sundog or parhelion, the paraselene is produced by moonlight shining through thin, hexagonal-shaped ice crystals in high cirrus clouds. 类似环日的形成一样,在高空卷云中,月光通过稀薄、具有六边形状的冰晶时产生了幻月。
During this alignment, each crystal can act like a miniature lens, refracting sunlight into our view and creating phenomena like parhelia, the technical term for sundogs. 在这个平面内,每一个冰晶就像一个小透镜一样,将太阳光折射入我们的视野,造成幻日现象,其术语就是幻日。
