abstract. A number of events in which oscillations in the solar wind plasma are correlated with Pc5 pulsations observed by SuperDARN radars have been identified. Magnetic field, velocity, thermal pressure and density data from the ACE and WIND satellites are analysed using sophisticated multiple taper techniques to provide complex demodulated time series of the oscillations. The energy flux, energy density, and polarization of the signals are used to determine the physical nature of the waves.
