The signals of the American satellite Explorer 22 on 20, 40, 41 Mc/s have been received and their amplitudes recorded. The records show the Faraday effect when a fixed linearly polarized antenna is used. Using the Faraday effect, the total electron content can be computed, the total number of rotations being determined by comparing records of 40 and 41 Mc/s. The considerations of this paper are based upon the period January‐April 1965. Total electron content decreasing to the north prevail. In addition, a comparison of the Faraday effect on 20 and 40 Mc/s was performed. At small zenithal distances the Faraday periods on both frequencies (reduced to the same frequency) become equal; at larger distances typical deviations are observed.
