A solar phenomenon known as a sundog arcs over the tundra in Churchill, Manitoba, Canada.

/ 太阳的“假日”天文现象半悬于加拿大Manitoba丘原的天际。

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，高空卷云中，光通过稀薄、具有六边形状的冰晶时产生了幻。

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.

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。
