Delta Sunspot

  • Released Thursday, January 21, 1999

When a large bundle of magnetic field lines breaks through the Sun's surface, a sunspot can form. Sometimes, a smaller spot will emerge nearby, creating a magnetically complex region where particles are energized and then violently expelled. Supercomputer models show that rearranging magnetic field lines enables this process.

A animation of the magnetic field of a sunspot, where the magnetic field at the Suns surface is colored blue for strong fields pointing into the sun and red for strong fields pointing out of the Sun. The white lines represent magnetic field lines.
