Video: Dancing Spiral Magnetic Loops on the Sun

by Nancy Atkinson on April 10, 2011

Cascades of spiraling magnetic loops observed in extreme ultraviolet light by Solar Dynamics Observatory danced and twisted above an active region on the Sun recently (April 3-5, 2011). These loops are charged particles spinning along the magnetic field lines. The bright active region was fairly strong and the activity persistent, though not explosive. At one point darker plasma can be seen being pulled back and forth across the region’s center.
