Consideration is given to Alfven disturbances arising from a field-aligned current encountering an anomalous resistivity layer with time-varying conductivity. The analytical investigation was spurred by the detection of regions of reduced conductivity in the auroral zone of the magnetosphere, which have been associated with energetic field-aligned particle fluxes, inverted-V electron precipitation, and 10 kV potential differences. Attention is devoted to wave propagation in half-spaces with infinite parallel conductivity. A boundary condition is obtained for a thin layer with anomalous resistivity. The generation of Alfven waves is described for an arbitrary dependence of the parallel conductivity of the layer in time and on the transverse coordinates. The magnetic field passing through the layer localizes the disturbances. Pi2 pulsations recorded on earth are generated by a standing Alfven wave produced by the emergence of an anomalous resistivity above a suddenly flashing auroral arc.
