Abstract : Advances were made in understanding of solar-wind magnetosphere interactions and the influence of the solar wind on geomagnetic activity. These advances cover a broad range of topics, including empirical studies of the solar-wind control of geomagnetic activity, theoretical studies of the coupling of solar-wind energy into the magnetosphere, observational and theoretical studies of the dynamics of the plasma sheet and its role in magnetospheric substorms, and investigations of the coupling between the magnetosphere and the ionosphere. As a direct result of this research, a limited capability was developed of predicting geomagnetic activity using parameters measured in the upstream solar wind. Journal publications supported by the contract are reproduced in order to provide a complete reporting of the salient results of contract-supported research. The report is divided into three subject categories: Part I -- Solar-Wind Magnetosphere Interactions; Part II -- Magnetosphere Tail; and Part III -- Magnetosphere-Ionosphere Interactions. The report also includes a few papers that were not supported directly by this contract; these papers represent the completion or significant extension of work that was initiated at Rice University under contract funds.
