Scientific paper

We study the spectral properties of different regions and structures in the Energetic Neutral Atom (ENA) maps at energies between ~0.5 keV and ~6 keV (FWHM) from the Interstellar Boundary Explorer (IBEX) mission. Our study confirms that the ecliptic latitude predominantly orders the spectral signatures of ENA distributions. This latitudinal ordering may reflect average solar wind properties that vary characteristically with latitude around solar minimum. The tail region shows the clearest latitudinal evolution with an inflection point between ~ 45° S and ~33° N latitude, which is strongly correlated with the solar wind speed variations obtained by Ulysses/SWOOPS instrument during its fast latitude scan in 2007. We report on the spectral analyses of nine regions in the IBEX maps. We also discuss the small-but-consistent spectral differences between the Northern and Southern polar regions in both the noseward and tailward directions, which also correlate with the time-evolution of the polar solar wind velocities reported earlier by Ulysses.
