Active Region Coming Around the Bend

April 23, 2018
A good-sized active region with bright, towering arches began to rotate into NASA's Solar Dynamics Observatory's view (Apr. 18-19, 2018).

A good-sized active region with bright, towering arches began to rotate into view (Apr. 18-19, 2018). The arches consist of charged particles spiraling along magnetic field lines revealed in this wavelength of extreme ultraviolet light. They rise up above the sun's surface many times the size of Earth. The video covers just 16 hours of activity. We will keep our eyes on this region to see if it has the kind of dynamism to produce solar storms.
