A series of active regions were all lined up one after the other as they rotated into view over three days (Sept. 22-24, 2012). The gyrating loops above each of the regions seen in profile also add interest to the video clip and still image. Sometimes the magnetic field comes up into the corona from the lower regions and loops back down into the Sun. These were all taken in the 171 Angstrom wavelength of extreme ultraviolet light. Incidentally, the movie is comprised of over 460 images.
