    This paper reviews the state of knowledge concerning the source of magnetospheric plasma at Earth. Source of plasma, its acceleration and transport throughout the system, its consequences on system dynamics, and its loss are all discussed. Both observational and modeling advances since the last time this subject was covered in detail (Hultqvist et al., Magnetospheric Plasma Sources and Losses, 1999) are addressed

    Conjugacy of Auroral Oval

    Results of statistical studies so far made hitherto on the auroral ovals in the northern and southern hemispheres are reviewed. Then, a same analysis method is applied on both northern and southern optical auroras to identify the auroral ovals as a function of magnetic activities. The result shows that a good geomagnetically conjugate relationship of the auroral oval is established. In the end, the configurations of the northern auroral oval at different universal times for different magnetic activities are projected along the real magnetic field lines onto the southern hemisphere surface
