一条砾石小路蜿蜒穿过这片色彩斑斓的乡村夜空。这张照片摄于10月10日晚，摄于西弗吉尼亚州南部的门罗县，星空是我们熟悉的景象。不过，闪烁的北极光在这里绝对不会经常出现。令人惊讶的是，那天晚上，在全球极低纬度地区出现了生动的极光，远离了通常的南北高纬度地区。广泛的极光活动是由日冕物质抛射（CME）的影响引发的严重地磁风暴的证据，日冕物质抛射是一种巨大的高能等离子体磁化云。CME是在一次强大的x级太阳耀斑之后从活跃的太阳向地球发射的。成长画廊：2024年10月10日至11日期间的全球极光

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
