A coronal mass ejection erupts from the Sun and propagates out through the Solar System. Along the way it is detected by the spacecraft at Jupiter and Saturn. Eventually it is detected by the two Voyager spacecraft beyond the orbit of Pluto. This animation is based on CMEs produced during the Halloween storms of 2003. It is an update to a previous animation.
