[漢羅] 縮時攝影影片：極光、SAR 弧、kah 銀河

Tī 這个無四常 ê 暗暝天頂是發生啥物代誌？ 這是一支 濃縮 4 點半鐘 ê 360 度 全景 影片，上引人注意 ê 部份，應該是 粉紅仔色 kah 茄仔色 ê 極光。 5 月 11 這暗 ê 極光，實在是世界 有名--ê。 等到暗暝 ê 時陣，極光帶出現 tī 天頂 閃閃爍爍，銀河系 ê 中央帶 沓沓仔 peh 懸，恆星嘛因為 地球自轉 tī 天頂徙位。 影相有同齊翕著 tī 極光頂懸 真罕得看著 ê 紅色光帶，tī 天頂沓沓仔咧變化。 這就是 SAR 弧，穩定極光紅弧。 地平線以下 ê 爍光，是因為有車駛過去。 天頂會振動 ê 光點，是衛星 kah 飛龍機。 這支影片是 tī 中國 新疆 用 4 台獨立 ê kha-mé-lah 翕出來--ê。

[English] Timelapse: Aurora, SAR, and the Milky Way

What's happening in the sky this unusual night? Most striking in the featured 4.5-hour 360-degree panoramic video, perhaps, is the pink and purple aurora. That's because this night, encompassing May 11, was famous for its auroral skies around the world. As the night progresses, auroral bands shimmer, the central band of our Milky Way Galaxy rises, and stars shift as the Earth rotates beneath them. Captured here simultaneously is a rare red band running above the aurora: a SAR arc, seen to change only slightly. The flashing below the horizon is caused by passing cars, while the moving spots in the sky are satellites and airplanes. The featured video was captured from Xinjiang, China with four separate cameras.
