A G3 geomagnetic storm is predicted to strike Earth, with displays of the Northern Lights possible across northern U.S. states.

When this solar flare was released, a CME followed shortly after. CMEs usually arrive at the Earth several days after a solar flare, and can trigger geomagnetic storms if they collide with the ...
