Fig6_15 Magnetic Cloud

Fig. 6.15 . When a coronal mass ejection travels into interplanetary space, it can create a huge magnetic cloud containing beams of electrons that flow in opposite directions within the magnetic loops that are rooted at both ends in the Sun. The magnetic cloud also drives a shock ahead of it. Magnetic clouds are only present in a subset of observed interplanetary coronal mass ejections. (Courtesy of Deborah Eddy and Thomas Zurbuchen.)
