一條碎石鄉間小道緩緩蜿蜒，穿過這幅色彩斑斕的鄉村夜景。這是 10 月 10 日晚從西弗吉尼亞州南部門羅縣拍攝的照片，上面的星空似曾相識。不過，閃閃發光的極光或北極光絕對不會在這裡經常出現。令人驚訝的是，當晚全球極低緯度地區都出現了生動的極光現象，與通常的南北高緯度地區相去甚遠。日冕物質拋射（CME）是一種巨大的磁化高能等離子體雲，它的撞擊引發了嚴重的地磁暴。日冕物質拋射是在強烈的 X 級太陽耀斑之後從活躍的太陽向地球發射的。 成長相簿： 2024 年 10 月 10 / 11 日期間的全球極光
原文：A gravel country lane gently winds through this colorful rural night skyscape. Captured from Monroe County in southern West Virginia on the evening of October 10, the starry sky above is a familiar sight. Shimmering curtains of aurora borealis or northern lights definitely do not make regular appearances here, though. Surprisingly vivid auroral displays were present on that night at very low latitudes around the globe, far from their usual northern and southern high latitude realms. The extensive auroral activity was evidence of a severe geomagnetic storm triggered by the impact of a coronal mass ejection (CME), an immense magnetized cloud of energetic plasma. The CME was launched toward Earth from the active Sun following a powerful X-class solar flare. Growing Gallery: Global aurora during October 10/11, 2024
