What's behind the northern lights that dazzled the sky farther south than normal

The latest solar storm has triggered northern lights farther south than normal including into parts of Germany, the United Kingdom, New England and New York City. There were no immediate reports of disruptions to power and communications from Thursday’s storm. Friday forecast shows continued higher-than-normal activity, but the chances for another overnight show are slim farther south of Canada and the northern Plains states. The sun is near the peak of its current 11-year cycle, sparking all the recent solar activity. In May, Earth got slammed by severe solar storms, the strongest in more than two decades.
