The power of two Pi 2 pulsations observed near the eastward electrojet by the Scandinavian Magnetometer Array, calculated by a standard FFT method, is noted to peak near the center of the eastward electrojet. Both events exhibit a strong latitudinal gradient in the power poleward of the equatorward border of the electrojet. While polarization reversal occurs at higher latitudes in the western half of the array, that of the second occurs at higher latitudes at the edges of the array. A simple model of the ionospheric electric field, in accord with field line resonance theory, reconstructs the basic features of the observed Pi 2 equivalent current system. It is concluded that Pi 2 signatures in the region of the eastward electrojet, and far from the auroral breakup region, are governed by the field line resonance mechanism.
