Magnetic Arcade

(Solar Arcade)
(series of arch-like magnetic flux lines on the Sun)

A Magnetic Arcade (or Solar Arcade) is a tube-like configuration of Magnetic Flux topology associated with some Coronal Mass Ejections. It consists of Flux lines arching off the Sun and back (Coronal Loops) arranged in a series so as to form an "arcade" appearance. The topology can lead to Magnetic Reconnection and Solar Flares.
