Researchers from the Radiation Belt Storm Probes' Electric and Magnetic Field Instrument Suite and Integrated Science (EMFISIS) team at the University of Iowa have released a new recording of an intriguing and well-known phenomenon known as "chorus," made on Sept. 5, 2012.
The Waves tri-axial search coil magnetometer and receiver of EMFISIS captured several notable peak radio wave events in the magnetosphere that surrounds Earth. The radio waves, which are at frequencies that are audible to the human ear, are emitted by the energetic particles in Earth's magnetosphere.
