Magnetohydrodynamic wave phenomena have been investigated in the deep plasmasphere by the electric field measurements in the EXOS-D(Akebono) satellite. EXOS-D has highly eccentric orbits(the perigee: 274km. the apogee: 10. 500km). https://www.jmannino.com/great-save-Camiseta-Groves-de-corte-ajustado-con-ribete-de-algod-n-org-nico-Saxe-super-grab/
