#CME IMPACT SPARKS EUROPEAN #AURORAS: A CME struck Earth's magnetic field on Nov. 25th, sparking 15 hours of geomagnetic storms. At the apex of the G2-category event, auroras were observed across most of Europe, visible to the naked eye despite nearly full moonlight. Graeme Whipps, who sends this picture from Aboyne, Aberdeenshire, #Scotland (+57N):
Note that Whipps' photo includes a vertical band of rare orange auroras. "What an incredible sight!" Whipps says.
Usually, when auroras visit Europe, they stop in places like Scotland, going no farther south. On Nov. 25th, however, the lights descended all the way to Italy
