STUDY OF MICROPULSATIONS OF ABOUT 1 CYCLE PER SECOND.

Abstract

An analysis is made of several possible sources for geomagnetic micropulsations of about one cycle per second. These include hydromagnetic waves propagated downward from the magnetospheric boundary, natural resonance of the ionospheric current system, sudden changes in ionospheric parameters, and the effect of meteors. The attenuation of hydromagnetic waves is calculated for an ionospheric model that include heavy negative ions. The results are inconclusive because of the technical difficulties involved in obtaining the mathematical solution. Resonance phenomena are found to produce effects at frequencies far removed from the one-cycle region. Meteor effects are a possible source of micropulsations at one cycle, and a detailed analysis is made for this case. (Author)
