Scientific paper

The energy dependence of the equatorward cutoff of diffuse auroral precipitation is examined for both electrons and ions in the dawn, dusk, prenoon, and premidnight sectors. The data are taken from the DMSP F6 and F7 low-altitude polar-orbiting satellites with a 101-min period. It is found that the energy dispersion of equatorward cutoffs is fundamentally incompatible with the predictions of steady-state Alfven layers, particularly in that the sense of dispersion that such models predict for ions is virtually never observed. The assumption that the boundaries are formed by precipitation losses at the strong diffusion rate does much better in predicting the dispersion senses, but such models still cannot explain the observation that during very quiet times the dispersion tends to zero, especially for the ions.
