Scientific paper

Data from a low altitude polar orbiting satellite, on auroral protons with energy higher than 115 keV in the evening and forenoon sectors, are presented. In the forenoon sector there is a weak but fairly steady precipitation at 75 deg invariant latitude during quiet conditions. In the evening sector a rather sharp equatorward boundary of the main precipitation, at 69 deg invariant latitude during quiet conditions, varies fairly smoothly from pass to pass. The equatorward boundaries of the main precipitation at both local times move equatorward with increasing ring current strength. From an attempt to reveal some of the substorm-dependent changes of the precipitation it is found that an equatorward shift of the precipitation areas takes place during, or just prior to, the substorm expansive phase, accompanied by a large intensity increase in the evening sector, whereas the recovery phase is linked with a poleward expansion of the precipitation at both local times.
