The ATS-6 radio beacon experiment carried out at Aberystwyth 52.42 N, 4.05 W is described. A preliminary analysis of the data is described concentrating on hourly values of total electron content N sub T, Faraday content N sub F, protonospheric content N sub P and layer shape F-factor. The monthly media behaviour of the parameters is discussed together with the effects of observational and analysis error on the accuracy of the protonospheric content values. The correction for layer height changes has been found to be of much less importance for European stations observing during Phase II ATS-6 operations than for measurements made in America during Phase I. The dynamic interchange of plasma between ionosphere and protonosphere has been studied by estimating hourly values of average integrated net fluxes from the temporal gradient of protonospheric content. The protonospheric flux data have been interpreted qualitatively in terms of diffusive interaction between ionosphere and protonosphere in both local and conjugate hemispheres. Added confirmation is obtained by consideration of contrasting protonospheric data from an American sector station which can also be related to ionospheric behaviour in the two hemispheres.
