Uploader comment: A pair of significant active regions that were coming into view put on a dazzling display with a canopy of magnetic loops (January 5-7, 2013). The arcs, seen here in extreme ultraviolet light, are charged particles spinning along the magnetic field lines emanating from these active regions.
