Solitary and paired electromagnetic structures were observed aboard the AUREOL-3 satellite in the auroral ionosphere. Within and very near these structures strong localized fluxes of accelerated field-aligned electrons and transverse O+ and He+ ions were detected, together with narrow electrostatic and whistler-mode wave beams and plasma density perturbations. The data are interpreted in terms of oblique non-linear Alfvén waves that accelerate and transport particles creating a set of oblique auroral rays and structured ELF/VLF emissions.
