Magnetic Arcade

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

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