| Abstract: | By the application of dispersion analysis to records of interplanetary scintillation taken from a triangular arrangement of receivers, it is found that the velocity of drift of the diffraction pattern increases with temporal frequency of different Fourier components of the pattern. Part of the observed dispersion is believed to arise as a result of integration along an extended line of sight but the possibility exists of a contribution from the interplanetary medium itself. Such an effect, if confirmed by further observations, would imply the existence of structures in the solar wind travelling at enhanced velocity relative to the mean flow. |
