[漢羅] STEVE 極光：發光 ê 河川

有當時仔，天頂會出現一條燒熱 ê 河。 這條河會製造 速度增加的強熱輻射，抑是叫做 STEVE 極光，會發出紅色、白色、kah 粉紅仔色 ê 光。 STEVE 極光 是 按怎出現欸？ 這到今猶是一个研究主題。 毋過最近 ê 證據表示講，in 是 ùi 地球大氣 100 公里懸 ê 電離層 內底 高速運動 ê 熱離子河 發光 造成--ê。 較闊 ê 紅光河川，可能 kah STEVE 極光 有關，毋過嘛有可能是 穩定極光紅弧 SAR，這是一款 較捷 看著 ê 光。 這張相片 是這個月 tī 法國 Côte d'Opale 翕--ê 闊幅數位合成相片，變做天頂 ê STEVE 極光弧。 雖罔講這个 幻影 才出現幾若分鐘久，毋過 tùi 頭腦動足緊 ê 天文攝影師來講，已經有夠矣！ 毋知你有揣著伊無？

[English] STEVE: A Glowing River over France

Sometimes a river of hot gas flows over your head. In this case the river created a Strong Thermal Emission Velocity Enhancement STEVE that glowed bright red, white, and pink. Details of how STEVEs work remain a topic of research, but recent evidence holds that their glow results from a fast-moving river of hot ions flowing over a hundred kilometers up in the Earth's atmosphere: the ionosphere. The more expansive dull red glow might be related to the flowing STEVE, but alternatively might be a Stable Auroral Red (SAR) arc, a more general heat-related glow. The featured picture, taken earlier this month in Côte d'Opale, France, is a wide-angle digital composite made as the STEVE arc formed nearly overhead. Although the apparition lasted only a few minutes, this was long enough for the quick-thinking astrophotographer to get in the picture -- can you find him?
