The authors report on data collected by the DE 1 satellite on several near crossings of the auroral kilometric radiation (AKR) source in the nightside auroral region. Plasma instruments aboard the high altitude satellite observed regions with strong perpendicular heating (T[sub [perpendicular]]/T[sub [parallel]] > 10) either within or adjacent to the source region. The satellite also observed loss cone effects, trapped particles, beams, and electron conical distributions in the same general region. The authors argue that wave-particle interactions have strongly modified the electron distribution properties. These observations are compared with recently published numerical simulations.
