這似乎是一個夜晚，但部分天空發出了紫色的光芒。 這是 2024 年 5 月 10 日著名的夜晚，當時世界上許多地方的人們都報告說天空中出現了美麗的極光。這張照片是這一夜凌晨從美國威斯康星州阿靈頓拍攝的。這幅全景圖是由幾張 6 秒鐘曝光的照片合成的，覆蓋了三分之二的可見天空，以北為中心，經過處理後色彩更加鮮豔，電線也被去除。攝影師（前景）報告說，極光似乎從頭頂的一個點流過，但只照亮了向北的天空。極光的高能粒子來自幾天前太陽黑子 AR 6443 上噴出的集合放射粒子。這個大的活躍區域上週旋轉到了太陽的遠端，但下週很可能繼續向地球旋轉。
原文：It seemed like night, but part of the sky glowed purple. It was the now famous night of May 10, 2024, when people over much of the world reported beautiful aurora-filled skies. The featured image was captured this night during early morning hours from Arlington, Wisconsin, USA. The panorama is a composite of several 6-second exposures covering two thirds of the visible sky, with north in the center, and processed to heighten the colors and remove electrical wires. The photographer (in the foreground) reported that the aurora appeared to flow from a point overhead but illuminated the sky only toward the north. The aurora's energetic particles originated from CMEs ejected from our Sun over sunspot AR 6443 a few days before. This large active region rotated to the far side of the Sun last week, but may well survive to rotate back toward the Earth next week.
