[漢羅] Tī 瑞典天頂看起來敢若旗仔 ê 極光

伊干焦出現一目-nih，to̍h 親像一支 50 公里懸 ê 長長 ê 旗仔。 Tī 2015 年三月中，能量足強 ê 日冕物質噴出事件 直接 tùi 地球磁場 ê 閬空送過去。 予地球產生一个 tī 最近幾若年來，上強 ê 地磁風暴。 這个結果煞予咱 tī 地球磁極 附近幾若个國家 ê 天頂，看會著 足闊 ê 極光現象。 這張影像是 tī 瑞典 ê Kiruna 城鎮翕--ê。 Tī 遮 ê 天頂有特別直 ê 極光 kha-tián。 這个 青色 ê 發射光是 tī 地球大氣層 ê 低層，紅色 ê 發射光是 tī 頂層幾若公里懸 ê 所在。 是講咱猶毋知影這个足罕得看著 ê 茄仔色極光，是 ùi 佗位來--ê。 毋過咱可能會 tī 比青色極光閣較低海拔 ê 所在，看著反常 ê 藍色極光。 閣 tī 頂層疊閣較懸 ê 紅色極光。 是講，這馬才拄仔過 太陽極小期。 紲落來，地球頂懸有 極光 ê 彩色 暗暝 嘛會愈來愈濟。

[English] A Flag Shaped Aurora over Sweden

It appeared, momentarily, like a 50-km tall banded flag. In mid-March of 2015, an energetic Coronal Mass Ejection directed toward a clear magnetic channel to Earth led to one of the more intense geomagnetic storms of recent years. A visual result was wide spread auroras being seen over many countries near Earth's magnetic poles. Captured over Kiruna, Sweden, the image features an unusually straight auroral curtain with the green color emitted low in the Earth's atmosphere, and red many kilometers higher up. It is unclear where the rare purple aurora originates, but it might involve an unusual blue aurora at an even lower altitude than the green, seen superposed with a much higher red. Now past Solar Minimum, colorful nights of auroras over Earth are likely to increase.
