说明: 北极光降临佛罗里达的夜空。事实上，在这张摄于11月11日佛罗里达州希尔德岛（Shired Island）的海天相接照片中，一颗耀眼的北金牛座流星划过繁星点点的夜空，照亮了海滩上方。每年这个时候，北金牛座流星雨的流星如期而至。然而，数位相机的曝光也记录下了极光的闪烁光芒，这种现象通常在地球较高纬度的地区才能看到。这些北极光，也称为极光，是近期大规模 极光活动的一部分，这些活动是由强烈的地磁风暴引起的。在过去的几天中，风暴性的太空天气是由多次冲击地球的日冕物质抛射和强烈的太阳活动所触发的。

Florida Northern Lights

Explanation: Northern lights have come to Florida skies. In fact, the brilliant streak of a Northern Taurid meteor flashes through the starry night sky above the beach in this sea and skyscape, captured from Shired Island, Florida on November 11. Meteors from the annual Northern Taurid meteor shower are expected this time of year. But the digital camera exposure also records the shimmering glow of aurora, a phenomenon more often seen from our fair planet’s higher geographical latitudes. Also known as aurora borealis, these northern lights are part of recent, wide spread auroral activity caused by strong geomagnetic storms. In the last few days, stormy spaceweather has been triggered by multiple Earth impacting coronal mass ejections and intense solar activity.
