Data from the second flight of the Aries Porcupine sounding rocket campaign are presented and analyzed. The data reveal auroral electrons with spectral peaks at energies up to 4 keV and the dc electric field shows a remarkable degree of anticorrelation with the peak electron energy. Electron precipitation data are used as input to a numerical simulation of the auroral ionosphere to calculate ion production rates. From these and the recombination rates, the equilibrium electron density is calculated, properly accounting for the effective drift velocity of ionization from its point of production. Using the classical formulas, the Pedersen and Hall conductivities in the neutral frame are then calculated. Finally, various combinations of the arc motion velocity and neutral wind velocity are used to compare the resulting electric field component normal to the arc with the observations. The results imply that the ionization produced by the auroral electrons does not move with the E¿B drift velocity, perhaps the result of a larger collisional coupling to neutrals than expected. A relationship is obtained between the components of the neutral wind velocity parallel and perpendicular to the arc. The observed anticorrelation is attributed to the blockage of field-aligned current and the resulting polarization of the ionosphere as well as the relatively linear relationship between peak electron energy and height integrated conductivity for peak energies below a few keV.
