Aurora Over Quebec

Auroras produce green curtains of light August 4 across the Rupert River in Waskaganish, a Cree Nation community in Quebec, Canada.
Last week's northern lights—which held up a few days—were productions of a big break of plasma, or charged gas, from the sun called a coronal mass ejection. A NASA orbiter named the Solar Dynamics Observatory witnessed last Sunday's eruption, which was placed straight at Earth and sparked predictions of a shimmering sky appearance.
Now it appears aurora fans possibly in for another treat: A solar flare stained Saturday by NASA's Solar and Heliospheric Observatory was even more muscular than the previous eruption. Though this time the majority of the plasma burst isn't calculated right at Earth, scientists say it could still trigger another around of colored auroras.
