On July 5, 2017, NASA’s Solar Dynamics Observatory watched an active region — an area of intense and complex magnetic fields — rotate into view on the Sun. 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. This image shows a blended view of the sunspot in visible and extreme ultraviolet light, revealing bright coils arcing over the active region — particles spiraling along magnetic field lines.
