Data obtained on November 2, 1977 with the propagation density experiment and the UCLA magnetometer aboard the ISEE 1 and 2 spacecraft are analyzed to investigate quantitatively the correlation between the fluctuations in the electron density and magnetic field in the proton foreshock. This analysis confirms the earlier identification of the 'discrete wave packets' as whistler mode waves. After consideration of the most appropriate value for the unperturbed magnetic field B0, it is shown that the well known 'shocklet' structure consists of finite amplitude, linearly polarized, simple, fast mode waves, separated by rotational discontinuities. The observations are compatible with waves propagating along a direction inclined to B0 at the angle predicted by a refraction model. There is some evidence that the observed deviations from quasi-unidimensionality are due to a finite amplitude instability.
