During the campaign devoted to the study of the auroral plasma, both active and passive wave measurements were performed aboard two sounding rockets as they passed through auroral forms. In the active experiment, the waves were excited by means of a radio-frequency probe of the quadripolar type. Very fine interference structure in the received signal was observed; particularly in the presence of precipitating electrons. Electrostatic waves are excited below the third harmonic of the electron gyrofrequency (FB). In the passive experiment, the cross-spectrum of natural random electrostatic waves received on two antennas were measured. Natural emissions around f sub b/2, 3f sub b/2 and around the upper hybrid frequency (fUH) were observed. The amplitudes of these emissions are above the thermal level of the plasma, but they correspond to a very low turbulence level.
