Auroral kilometric radiation (AKR) refers to a type of radio emission observed in the Earth's magnetosphere, typically generated during auroral activity. These emissions, occurring at frequencies between 0.1 and 1 MHz, are closely associated with the acceleration of electrons in the magnetosphere, particularly in the auroral zones where energetic particles collide with atmospheric atoms. AKR serves as a key indicator of processes within the magnetosphere and provides insight into interactions between solar wind and Earth's magnetic field.
congrats on reading the definition of Auroral Kilometric Radiation. now let's actually learn it.
