Analogous to a sundog or parhelion, the paraselene is produced by moonlight shining through thin, hexagonal-shaped ice crystals in high cirrus clouds.

类似环日的形成样，在高空卷云中，月稀薄、具有六边形状的冰晶产生了幻月。

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.

在这平面内，冰晶就像小透镜样，将太阳折射入我们的视野，造成幻日现象，其术语就是幻日。
