美国佐治亚州的极光

Explanation: A familiar sight from Georgia, USA, the Moon sets near the western horizon in this rural night skyscape. Captured on May 10 before local midnight, the image overexposes the Moon’s bright waning crescent at left in the frame. A long irrigation rig stretches across farmland about 15 miles north of the city of Bainbridge. Shimmering curtains of aurora shine across the starry sky though, definitely an unfamiliar sight for southern Georgia nights. Last weekend, extreme geomagnetic storms triggered by the recent intense activity from solar active region AR 3664 brought epic displays of aurora, usually seen closer to the poles, to southern Georgia and even lower latitudes on planet Earth. As solar activity ramps up, more storms are possible.

说明: 这是一片很熟悉的美国佐治亚州景观：乡村夜空中的月亮落向西方的地平线。在这幅摄于5月10日当地子夜前的影像里，视野左侧的明亮残月过度曝光，而更有一座长长的移动式喷灌设备，横跨在贝恩布里奇市北方约24公里处的这片农田上。不过，对佐治亚州南部的夜晚来说，星空中摇曳的极光帘，无疑是很陌生的景观。在上个周末，由太阳活跃区AR 3664近来的强烈活动所触发的极端地磁风暴，让通常只有在南北极地区才得见的壮丽极光活动，出现在佐治亚州南部及更低纬度的地区。随着太阳的活动增加，地球可能会发生更多的磁暴。
