Abstract
Various wave and particle observations on auroral field lines made by the Swedish magnetospheric research satellite Viking are discussed with an emphasis on ion wave instabilities and production of conical ion distributions. Examples of ion waves driven by free energy sources such as particle beams and ion loss cone distributions are presented. Observations of ions that are accelerated locally transverse to the magnetic field close to the polar cusp field lines at altitudes from 10000 to 13500 km are presented with simultaneous wave measurements. The observations are discussed in the light of earlier simulation studies and their impact on future simulations is considered.
