This figure illustrates the effect of an interplanetary shock impacting on the Earth's magnetosphere.

The red curve symbolises the Earth's bow shock. The relative positions of a number of satellites studying the Sun-Earth region are indicated. The propagation speed and direction of the wave front induced by the shock have been determined thanks to the data collected by this armada of spacecraft.
