Abstract
A study has been made of the correlation of the population of relativi stic electrons in the outer-zone magnetosphere with the properties of the solar wind (speed, density, magnetic field) during a solar minimum period, The study is based upon observations made in the Spring of 19 95 with sensors aboard 1994-026 and WIND. It is found that a large rel ativistic electron enhancement depends upon a substantial solar-wind s peed increase associated with precursor solar-wind density enhancement , and, in particular, upon a southward turning of the interplanetary m agnetic field.
