The illustration maps the magnetic field lines emanating from the Sun and their interactions superimposed on an extreme ultraviolet image from SDO (Mar. 12, 2016). The field lines are most dense around active regions, but they also link to other magnetically active areas across the Sun. Images like these can be found for every wavelength each day under the More Images link on the home page under The Sun Now image. These images are labeled PFSS and are available in different sizes. The movie shows the magnetic map overlaid on three extreme ultraviolet images and one magnetogram image (shows the magnetically active areas as black or white).
