Carl Like the title say, according to the forecast by US, 极光所覆盖的环形区域偏向North America. May you see that in China?
OOOO Some of my friends have seen the Aurora in UK. In the city I lived in(53.8N), the Aurora can hardly be seen by eyes(in the city), but it can be seen in some surburban area. I guess @suriana may have seen it last night.
