Measurements of the total ion concentration and of the transverse horizontal and vertical components of the ion convection velocity were obtained in October-November 1967 from the Cosmos 184 satellite, and 11 cases of sign reversal of the y component of the interplanetary magnetic field (reversal during the time interval between two successive satellite passes through the equatoral ionospheric anomaly) were studied. Changes in the near-equatorial ion density occurring in association with sign reversal are described, and the correlation of sign reversal with variation in the polar plasma drift data is indicated. The measurements support the propagation of the electric field variations from polar ionospheric/outer magnetosphere down to the equatorial latitudes, as was suggested by Rastogi and Patel (1975).
