Abstract : An attempt is made to explain the 'auroral afterglow' or short-duration afterglow of nitrogen, discovered in 1932 by Kaplan, in terms of well established processes. In this afterglow, N2+ bands are excited together with bands of neutral N2 molecules, which show energies far exceeding the limit evident in the well known long-duration afterglow (Lewis-Rayleigh afterglow). This limit is given by the energy of recombining N atoms, 9.76 eV. (Author)
