A recently reported standing Alfvén wave at ATS 6 is reinterpreted using axisymmetric toroidal‐mode solutions which involve realistic ionospheric height‐integrated conductivities. Details of possible wave‐forms are deduced, and it is suggested that the wave may be interpreted as either a modified form of the classical half‐wave resonance, or as an example of the recently predicted quarter‐wave resonance.
