Description:
The high latitude limit of transequatorial deuteron whistlers is found to occur at latitudes where B(m) = B/2, in which B is the local magnetic field at the satellite and B(m) is the minimum magnetic field on the field line through the satellite. The high latitude limit of transequatorial proton whistlers, often extends to the latitude where B(m) = B/4 in the autumn and winter. Transequatorial deuteron whistlers have a constant time interval for an echo train. The damping rate of the cyclotron resonant interaction with rare deuteron is large enough to generate deuteron whistlers. Ray tracing results for nonducted propagation of transequatorial deuteron whistlers show that rays are guided by the geomagnetic field within one degree in invariant latitude for several bounces between the two hemispheres.
