The last in a series of three coronal mass ejections hit Earth on Wednesday, so experts are keeping an eye on geomagnetic storm potential

The British Geological Society is warning that the Earth is about to get hit by the most powerful solar storm in over two decades.

The X5.1-class eruption from sunspot AR4274 is this year's most powerful solar flare and Earth is in the firing line.

Auroras might be seen again tonight, Wednesday, Nov. 12, across the nation thanks to another powerful coronal mass ejection that's headed for Earth.

The sky cleared enough Tuesday night to reveal a strong geomagnetic storm whipping by Earth at millions of miles per hour, prompting beautiful views of the northern lights across all six New England states. The purple, red, and green hues were easily visible to the naked eye and enhanced by smartphone cameras.
