Modelling structural peculiarities of electron density distribution in the plasmasphere

Based on the ionosphere- plasmasphere interaction model, we studied the electron density distribution structure peculiarities in the geomagnetic equator plane in the plasmasphere for two seasons at low and high geomagnetic activity, and for two Universal Time instants. The calculation results allowed us to investigate the variation in the shape and the size of the plasmapause at low and high geomagnetic activity against moderate solar activity.
