Magnetic Pc5 Pulsations Associated with Periodical Particle Precipitation
Kuwashima, M.
Abstract
 A degree of the contribution of the periodically precipitating charged particles to the generation of Pc5 is investigated using the data observed at Syowa Base (φm = 69.6) in 1968. As a result of the analysis it is supposed that the periodically precipitating particles can contribute to Pc5 as secondary effect, although the main cause of Pc5 may be the hydromagnetic wave.
Additionally the substorm is examined as a possible source of the hydromagnetic wave which is the main cause of Pc5 and the related particle precipitation.
