This aurora appeared over Marquette, Mich., on May 18, 2013, after coronal mass ejections, or CMEs, from the sun made contact with Earth's magnetic field, funneling energy and particles into near-Earth space. Image Courtesy of Amy Cherrette
The CMEs were associates with two X-class flares; an X3.2 on May 13, and an X1.2 on May 14. Both flares originated from active region 1748.
