• Artificial ionospheric optical emissions can be produced by high-power high-frequency (HF) radio waves. From the observation of HF induced artificial aurora on 21 February 1999, M.J. Kosch et al. (Geophys. Res. Lett., 27, 2817, 2000) first noted the equatorward displacement of the optical emission towards the magnetic field line direction. This effect is investigated further and does not appear to be related to either the ion drift or neutral winds. HF coherent radar backscatter observations are presented for the first time in conjunction with artificial aurorae. Ray tracing suggests that the optical displacement may be related to the mechanism for producing field-aligned irregularities, which the radars require for receiving backscatter. The altitude of the artificial aurora has been estimated and is shown to be well below the reflection altitude and upper hybrid resonance height of the pump wave.
