Abstract : This final report provides a summary of progress made during FY11 on the Air Force Office of Scientific Research task titled, Geospace Plasma Dynamics. The goal of this research effort was to develop a detailed knowledge of the space environment by analyzing satellite data and developing the theories needed to explain the observations. In this way we hoped to improve our capability to predict the state of the space environment. This effort included 2 basic research efforts. They were: (1) Investigate solar wind-magnetosphere-ionosphere coupling processes, and (2) Investigate the physics of the low-latitude ionosphere.
