The Faraday fading of a satellite signal has a fairly constant rate, except when the signal propagates through the ionosphere perpendicularly to the earth's magnetic field. At that instant, one notes a sudden slowing down of the fading rate. This usually occurs at receiving stations of low geomagnetic latitude. In this note, the duration of this sharp change in fading rate is calculated from the AppletonHartree formula for the refractive index (without collisions), near the transverse propagation conditions. Examples are given of amplitude records showing the “rate anomaly.”
