"Steve McGreevy is a sound recordist based in California. With the help of a special antennae and radio receiver, he listens to what's called chorus: the very low frequency electromagnetic waves which are created when charged particles from the sun reach the Earth's magnetic field." "What's happened is the sun has burped out a solar flare or what they call a coronal mass ejection. This energy travels several hundred kilometers per second and so eventually, within about twenty four hours or less, it impacts the Earth's magnetic field and causes it to pulsate. Imagine a bubble floating with wind currents pushing against it. You can see it deform. Well that's essentially what happens with Earth's magnetic field." "Once this energy from the sun collides with the Earth, it disturbs the Earth's magnetic field, generating the electromagnetic radio waves that we've been listening to."
