On the geomagnetic post-perturbation.
The character of the Geomagnetic Post-Perturbation, shows a decreasing in the daily means of the magnetic horizontal intensity at many observatories during several days following magnetic storm, is illustrated in this paper. As the general tendency, the amplitude of the Post-Perturbation decrease proportionally with latitude except near the auroral zone. Also, the decrease value of Post-Perturbation on the stations of same longitude shows rather good agreement with each other. From these results, it can be assumed that the current system of Post-Perturbation, is determined from several observatories in low and middle latitude except high latitude observatories, is similar to equatorial ring current system. Therefore the radius of equatorial ring current system by Post-Perturbation able to be determined from world wide distribution of magnetic intensity of Post-Perturbation. Analyzing much data in the worldwide, the results was obtained that the radius is about 20,000 km. It was found that this radius is equivalent to that of Van Allen Belts.
