The Freja TESP electron spectrometer has repeatedly observed ~100 eV-1 keV upward-directed, antifield-aligned electron beams near 1700 km altitude in the auroral zone. A particularly intense event, at energies up to 2 keV, is described. The beam perpendicular temperature T⊥e was as low as 0.1--0.2 eV at 100--200 eV parallel energy. The 10--15 s period of upward fluxes was coincident with a low density (~10 cm-3) period and a ~5 keV ion conic. Strong low frequency waves and the lack of any downward motion in the simultaneously observed ion conic suggest a strong element of wave acceleration, while electric field and ion loss cone measurements provide limited evidence of potential acceleration to a fraction of the observed energies. ¿ American Geophysical Union 1995
