A sunspot group's loopy magnetism

This is a composite animation showing the Sun as seen by two imagers on NASA's SDO satellite. One sees X-rays, where the Sun's magnetic field dominates, and the other visible light data. All three sections of the video are timed together; you can see the sunspot group evolve (growing, twisting, and rotating) on the lower right, and the associated magnetic loops responding on the upper right. These spots flared several times, and on March 15th let loose the first X-class flare of the new solar cycle.Video credit: Movie produced by D. Brown (UCLan).
