This movie from the Vlasiator computer model shows the kind of simple magnetic wave pattern that dominates the foreshock above Earth – the first region of our planet's magnetic environment that solar wind particles encounter – when space weather is calm. The size of the waves, and therefore their frequency, is the same throughout this region.
