Abstract Six north to south passes of the AUREOL 3 satellite through the equatorial electron density depletion at variable altitudes between 400 and 550 km, at night, during a two weeks period, exhibit similar features in plasma density irregularities which are thought to be associated with the spread F phenomenon. The irregularities are found to be quasi-monochromatic with a scale size of about 2 km along the satellite trajectory and occur only on the Northern edge of the equatorial electron density depletion. This implies a violation of the generally believed principle of conjugate mapping for those wavelengths. These observations are analysed and discussed in terms of different known generation mechanisms.
