Magnetic Arcs

May 29, 2013
An M5 flare (medium-size) associated with a coronal mass ejection generated a fairly robust radiation storm (May 22-23, 2013). The outburst originated from active region right near the right edge of the Sun. After the eruption, cascades of magnetic loops spun up above the area as the magnetic fields tried to reorganize themselves. When viewed in profile, they put on a marvelous display of solar activity. The images are a combination of two wavelengths of extreme ultraviolet light (at 171 and 304 Angstroms). Credit: NASA's Solar Dynamics Observatory.
