The Interstellar Boundary Explorer (IBEX) is a NASA satellite in Earth orbit, dedicated to observing both
interstellar neutral atoms entering the heliosphere and energetic neutral atoms (ENAs) from the interstellar
boundaries from roughly 10 eV to 6 keV. This work presents the averaged maps, energy spectra, and temporal
variability of heliospheric ENA intensities measured with the IBEX-Lo instrument at 1 au at energies between
10 eV and 2 keV, covering one entire solar cycle from 2009 through 2019. These results expand the range in time
and energy for studying the globally distributed ENA flux and the IBEX Ribbon. The observed ENA intensities
exceed model predictions, in particular below 500 eV. Moreover, the ENA intensities between 50–200 eV energy
show an unexpected rise and fall around the year 2015 in most sky regions.
