(a) Equatorial distribution of the Alfven speed A and the SMS waves speed C S across the magnetic shells (L = a/R E , R E is Earth radius). (b) Distribution across the magnetic shells of eigenfrequencies f SN = Ω SN /2π of the first three harmonics of standing SMS waves and the travel time along the field line between conjugate ionospheres t S at the SMS wave velocity C S .
