Every day scientists use their computer models to generate a view of the sun's magnetic field (Aug. 10, 2018). The bright active region right at the central area of the sun clearly shows a concentration of field lines, as well as the small active region at the sun's right edge, but to a lesser extent. Magnetism drives the dynamic activity near the sun's surface.
