Intensities of various optical emissions from mid-day auroras and spectral profile of N2(+) ING bands measured aboard a jet aircraft are presented. The data are compared with simple calculations based on present knowledge of the types and energy distributions of particles precipitating in the mid-day auroral region and the available cross-sections for the excitation of various optical emissions in air. The analysis concerns the interaction of magnetosheath protons with the atmosphere, electron interaction with the atmosphere, resonant scattering of sunlight by N2(+) ions, and auroral emissions around 3886 A. It is shown that most of the OI red and green line emissions in the mid-day aurora are excited by the low-energy electrons precipitating in the cusp region, but only part of the N2 and N2(+) emissions can be so accounted, while precipitating protons excite the rest of N2 and N2(+) emission. The emission feature around 3886 A observed in mid-day aurora is most likely He 3888 A blended with N2(+) ING(1, 1) band.
