Abstract 985 whistlers observed between 1970 and 1975 in Hungary have been processed for equatorial plasmaspheric electron density and tube electron content above 1000 km (NT). The hourly median value of NT exhibits a diurnal variation with an amplitude of 1×1013 electrons/cm2-tube. 75 per cent of the electron flux values obtained from the time variation of NT are lower than 6×108 el cm−2s−1, while in some cases the fluxes reach a value as high as 3×109 el cm−2s−1. Between 17 and 04 LT the dominant flux direction is toward the ionosphere. The data also indicate that the day to day filling of the plasmasphere after magnetic disturbances continues through several days without exhibiting saturation, with higher filling rates for lower values of average Kp.
