[漢羅] 寒天 ê 車路 kah 天頂 ê 四重月暈

有當時仔,落–落來 ê 冰晶予太氣層變做一个大透鏡,產生日頭 kah 月娘邊仔一輾 ê 光弧 kah 光暈。 2012 年寒天 ê 一个拜六暗,tī 西班牙 Madrid 附近 ê 天頂毋若出現一粒足光 ê 月娘,閣有四重足罕得看著 ê 月暈。 這張相片 中央上光翕粒 to̍h 是月娘。 月光去予落–落來 ê 六角形冰晶 屈折 了後,to̍h 會 tī 離月娘 22 度闊 ê 所在產生這个足罕得看著 ê 22 度月暈。 Tī 這个 22 度光弧水平方向閣較外口 ê 所在,有一輾閣較罕得看著 ê 外接月暈,是 柱仔形冰晶 造成 ê 現象。 閣較罕得看著 ê 是,有一寡月光去予閣較遠 ê 冰晶 屈折去,煞 tī 離月娘 46 度遠 ê 所在,產生第三重敢若虹 ê 光弧,to̍h 親像是這張 寒天天頂 ê 景色仝款。 而且,這个 離月娘 46 度遠 ê 圓箍仔月暈,大部份嘛攏看會著。 所以才會講,翕著這張 四重月暈 ê 相片,尤其是翕著月娘 ê,實在是真無簡單。 這張背景是一个足有名 ê 冬季天景,有 天郎星、kah 獵戶座皮帶、kah 參宿四。 In 攏 tī 內底彼輾光弧 kah 外口彼輾光弧之間揣會著。 月暈 kah 光弧會當擋幾若分鐘到幾若點鐘遐爾久。 你若是看著這个現象,猶會赴-lih 樓頂招樓跤、阿母招阿爸、厝邊招隔壁、朋友招親情,鬥陣做伙 來去欣賞這个 特別 ê 天景。

[English] Quadruple Lunar Halo Over Winter Road

Sometimes falling ice crystals make the atmosphere into a giant lens causing arcs and halos to appear around the Sun or Moon. One Saturday night in 2012 was just such a time near Madrid, Spain, where a winter sky displayed not only a bright Moon but four rare lunar halos. The brightest object, near the top of the featured image, is the Moon. Light from the Moon refracts through tumbling hexagonal ice crystals into a somewhat rare 22-degree halo seen surrounding the Moon. Elongating the 22-degree arc horizontally is a more rare circumscribed halo caused by column ice crystals. Even more rare, some moonlight refracts through more distant tumbling ice crystals to form a (third) rainbow-like arc 46 degrees from the Moon and appearing here just above a picturesque winter landscape. Furthermore, part of a whole 46-degree circular halo is also visible, so that an extremely rare – especially for the Moon – quadruple halo was captured. Far in the background is a famous winter skyscape that includes Sirius, the belt of Orion, and Betelgeuse – visible between the inner and outer arcs. Halos and arcs typically last for minutes to hours, so if you do see one there should be time to invite family, friends or neighbors to share your unusual lensed vista of the sky.
