Aurora Borealis Sound in real time

Northern Light Aurora Sound :

The Aurora Borealis is created by the solar wind hitting the earth's atmosphere. The charged particles of the solar wind are normally deflected away by the shield of Earth's magnetic field, but some are able to leak into the magnetosphere around the earth, where they are then guided along Earth's magnetic field to reach deeper into the atmosphere. Here they collide with the oxygen and nitrogen molecules of the air, to produce a luminous green and red glow that is the aurorae (Northern or Southern lights).
These moving charged particles that create the northern lights also produce intense radio emission at very low frequencies. We can 'hear' the aurorae as a busy chatter when these radio signals are converted to sound, varying on the real timescale that you can hear.
