Coronal Loops

festooningloopsAn active region of the sun just rotating into the view of the Solar Dynamics Observatory gives a profile view of coronal loops over about a two-day period, from 8  to 10 February, 2014. Coronal loops are found around sunspots and in active regions. The structures are associated with the closed magnetic field lines that connect magnetic regions on the solar surface. Some coronal loops can last for days or weeks, but most change quite rapidly. This image was taken in extreme ultraviolet light.
