Scientific paper

Measurements of energetic electrons from two rocket flights, both crossing discrete auroral arc structures, are examined with respect to low altitude parallel potential drops accelerating electrons of magnetospheric origin downward. In both flights the traversals of magnetic field lines connected to discrete auroral arc structures were associated with inverted V like electron spectral features with the highest peak energies closely related to the brightest auroral forms. The most equatorward inverted V structures, associated with the main arc, seems to mark a boundary south of which the magnetospheric electron population had a higher temperature than north of it. The magnitude and altitude of the potential drop can in principle be obtained by using a model for the acceleration applied to the observed energy and pitch angle distribution of the energetic electrons. A method to study the acceleration mechanism by means of some relations connected to integral flux measurements (energy flux and current density of energetic electrons) is also suggested.
