Observations made at dip latitudes of about 22 deg N and 12 deg S, of emissions excited by particle precipitation during magnetic activity show the first negative bands of N2(plus) to have a high degree of vibrational excitation at both sites. Together with the absence of H and He emissions, these data prompt an interpretation of the excitations as a consequence of precipitating O atom or ion flux, of which the former is more plausible, in turn caused by the charge exchange of ring current O(plus) ions with exospheric neutral constituents. Energy deposition and ionization production estimates are in the range 0.1-10 mW/sq m and 1-100 cu cm/sec, respectively.
