Experimental evidence is presented which shows small packets of electron plasma waves modulated by large amplitude obliquely propagating non‐linear ion plasma waves. Very often, but not always, the whole system is modulated by an oscillation near the ion gyro frequency or its harmonics. The ion waves seem to be similar to those measured in the current carrying auroral plasma. These results suggest that the generation of ion and electron waves in the auroral plasma may be correlated.
