Paper Abstract

EUV images from emissions of O+ (83.4 nm) and He+ (30.4 nm) distributions in the plasmasphere and trough regions are constructed for a satellite at 9 RE. A diffusive equilibrium model is used to describe the density distribution along field lines for ions in the plasmasphere while a kinetic collisionless model is assumed to calculate ion densities in the high latitude regions beyond the plasmapause. In our model of the plasmasphere we assumed that ions move along a static dipole field. Observational data on O+ and He+ densities in the ionosphere are used as boundary conditions to calculate spatial distribution of densities along field lines. Assuming that the day and night boundary conditions are asymmetric and exobase densities vary with latitude we will discuss how this would be reflected in the intensities and structure of the magnetosphere images.
