[漢羅] 月光下 ê 冰暈

北半球 4 月 15 月圓前後 ê 春天暗暝，tī 加拿大 Alberta 省 ê 天頂，出現這寡光閃閃 ê 幻影 。 這暗，光映映 ê 月光 kā tī 懸雲 ê 六角形冰晶 屈折 kah 反射去，產生這个 複雜 ê 月暈 kah 光弧。 一般講來，這款現象 tī 日時 ê 日光較看會著。 雖罔講光弧 kah 幻月（嘛叫做月狗） ê 色光，用目睭就會當直接看著。 毋閣這張闊幅 ê 月光天景，是 kā 30 秒到 1/20 秒 無仝感光時間 ê 相片組合起來 ê。 這幅圖頂懸 ê 北斗星，拄仔好 tī 咧微微仔笑 ê 環天頂虹弧 面頂。 月娘 ê 倒爿有大角星，正爿頂懸有軒轅十四。 伊就 tī 這个 22 度月暈 ê 中心。 5 月 15 這暗會閣拄著月圓，咱會當 tī 夜空看著光映映 ê 月光。 明仔載 ê 月圓會變較暗一段時間，因為月球會 ùi 地球烏影下底行過，產生 月全食。

[English] Ice Halos by Moonlight

An almost full moon on April 15 brought these luminous apparitions to a northern spring night over Alberta Canada. On that night, bright moonlight refracted and reflected by hexagonal ice crystals in high clouds created a complex of halos and arcs more commonly seen by sunlight in daytime skies. While the colors of the arcs and moondogs or paraselenae were just visible to the unaided eye, a blend of exposures ranging from 30 seconds to 1/20 second was used to render this moonlit wide-angle skyscape. The Big Dipper at the top of the frame sits just above a smiling and rainbow-hued circumzenithal arc. With Arcturus left and Regulus toward the right the Moon is centered in its often spotted 22 degree halo. May 15 will also see the bright light of a Full Moon shining in Earth’s night skies. Tomorrow’s Full Moon will be dimmed for a while though, as it slides through Earth’s shadow in a total lunar eclipse.
