Strongest solar flare of the summer sparks widespread auroras
An X-class solar flare that erupted on July 12 but was initially thought to have affected the earth only weakly revealed its full power on Saturday night in the form of displays of the Northern Lights that stretched as far south as Colorado and Arkansas.
In the southern hemisphere, auroras were observed from Australia, New Zealand, and even directly over the South Pole.
With the solar storm continuing, there is a possibility for auroras after dark on Sunday night as well.
