Beginning July 5, our Solar Dynamics Observatory watched a sunspot — an area of intense and complex magnetic fields — rotate into view. The satellite continued to track the region as it grew and eventually rotated across the Sun and out of view on July 17. With their complex magnetic fields, sunspots are often the source of interesting solar activity. During its 13-day trip across the face of the Sun, the active region — dubbed AR12665 — put on a show for our Sun-watching satellites, producing several solar flares, a coronal mass ejection and a solar energetic particle event.
