The satellite S3-3 data set was examined for examples of perpendicular ion acceleration with simultaneous broadband plasma-wave data. One event was found. Plasma waves in the frequency range for lower hybrid resonance (LHR) waves and in the frequency range for Doppler-shifted O(+) ion cyclotron waves modestly correlated with the perpendicular ion acceleration, although their electric-field amplitudes were less than that assumed in present theories of ion acceleration: about 0.2-6.0 mV/m (rms) for the LHR waves and 4-9 mV/m (rms) for the possible Doppler-shifted O/sup +/ cyclotron waves. Plasma waves propagating above the LHR frequency briefly reached a value of 10 mV/m (rms). No evidence was found for the existence of H(+) cyclotron waves during the period of perpendicular ion acceleration. The thermal or superthermal electron field-aligned current density (Ee < 170 eV), estimated by subtracting the current density measured by the electron spectrometer from that measured by the magnetrometer, correlated very well with the period of perpendicular ion acceleration.
