Summary

The paper discusses the evidence for magnetopause reconnection obtained from in situ plasma and energetic particle measurements onboard the International Sun-Earth Explorer satellites. The strongest evidence is provided by the test for tangential momentum balance between the plasma transmitted through the magnetopause and the sharply curved magnetic field. The test of the energy balance suffers from larger uncertainties, but still is consistent with momentum balance results. More indirect support is provided by tracing the magnetic field topology at the magnetopause with energetic particles. The solar wind plasma entering the magnetosphere forms a boundary layer which extends all along the magnetopause. Boundary layer observations indicate that reconnection is probably not the only interaction process operating at the magnetopause.
