The distorted ion velocity distribution associated with large ion drifts in the auroral F-region can drive ion cyclotron waves in the case of cold electrons. The Landau damping of the waves by the electrons is taken into account, and it is shown that the instability can be excited for all values of T-asterisk/Te, T-asterisk being the field-parallel ion temperature and Tc the electron temperature, and that the threshold value of the drift parameter D-asterisk is practically independent of the ion and electron temperatures for plasma with a single ion species, in contrast to the Post-Rosenbluth (1966) instability. A minimum value of T-asterisk/Te below which wave propagation would become impossible does not exist if a small deviation of the wave frequency from a multiple of the ion gyrofrequency is allowed for.
