Abstract : Measurements of total ionospheric electron content (TEC) by Faraday rotation of radio waves are given for the period November 1967 to September 1973 for 136 MHz transmissions from the geostationary satellite ATS-3 observed at a sub-ionospheric invariant latitude of 54 degrees N. The diurnal curves showed the effects of solar radiation and particle precipitation. (Modified author abstract)
