CAPTION On July 5, 2017, the Solar Dynamics Observatory watched an active region -- an area of intense and complex magnetic fields -- rotate into view. During its 13-day trip across the face of the Sun, the active region put on a show for several NASA Sun-watching satellites, producing several solar flares, a coronal mass ejection and a solar energetic particle event.
