TRAPPED CHARGED PARTICLES AS THE ORIGIN OF SHORT PERIOD GEOMAGNETIC PULSATIONS
Journal Article

· Planetary Space Sci.
A peculiar fan-shaped structure in the dynamic spectrum of short period geomagnetic pulsations with frequencies from fractions of a cps to several cps is interpreted theoretically. It is concluded that such geomagnetic pulsations are caused by hydromagnetic oscillations in the lower exospheric region excited by several bunches of charged particles, trapped in the Earth's magnetic field and moving with velocities of the order of several hundreds to a thousand kilometers per second.
