The plasmasphere is a region of ionospheric plasma which co-rotates with the Earth, carried by the magnetic field lines. This plasma tends to be colder (i.e. the ions have lower average energy) than the outer region of the magnetosphere. The plasmapause marks the outer boundary of this region. This visualization is a simple fly-around tour of the plasmapause (green) in a relatively quiescent state. For this visualization, the 3-dimensional structure was constructed from the equatorial profile of the plasmapause (as measured by IMAGE/EUV data) by extending the region along field lines of a simple dipole field.
