CME IMPACT: As predicted by analysts at the Goddard Space Weather Lab, a coronal mass ejection (CME) hit Earth's magnetic field at approximately 2145 UT on Nov. 28th. The impact was weaker than expected, but it still produced bright auroras around the Arctic Circle:

"The CME that hit Earth gave us some nice, colourful and easy-moving auroras," says photographer Antti Pietikäinen of Muonio, Lapland, Finland, who enjoyed the show with his two dogs.

Also in the Finnish Lapland, Chad Blakely says "the auroras exploded all over the sky. If this is a sign of things to come the rest of the season should be fantastic!!"

Not bad for a "weak impact."

都是因为磁北极和真北极不重合，磁北极在加拿大那边，导致大部分壮观的极光都发生在北美大陆，同纬度的俄国西伯利亚地区和远东地区就没有那么强烈的极光了，我国极北地区也没有多少机会能看到极光吧。。。。。
