The Saturn electrostatic discharges (SED) simultaneously recorded in the initial period of storm F at the UTR-2 radio telescope and Cassini spacecraft are investigated. The UTR-2 used the FFT-spectral receiver operating 12÷33 MHz, while the Cassini the serial spectrum analyser RPWS (Radio Plasma Wave Science) operating 1.8÷16 MHz. The ground and space data processed have shown very good agreement. E-folding time of SED and its dependence on episode intensity in the initial period of storm F were determined.
