A stability analysis of satellite-observed upgoing H(+) and O(+) beams in the auroral zone near midnight reveals the instability of an oblique H(+) acoustic mode. The wave involves a cyclotron resonance with O(+) and a Landau resonance with H(+). Interactions with this wave primarily involve a transfer of parallel H(+) streaming energy to perpendicular O(+) thermal energy. The rate of ion heating produced by such interactions is determined quantitatively in the context of quasi-linear theory.
