Arched Eruption


SDO caught a minor flare and a coronal mass ejection (CME) in profile as they blasted out from the Sun, producing a prominence that rose up and out in a curving arch (Sept. 8, 2010). The particle cloud was not aimed at Earth, so it could not produce geomagnetic effects on Earth. The stills show the arch in a wavelength of extreme ultraviolet (UV) light. The movie combines three wavelengths of extreme UV light and covers three hours of activity.
