Outer heliosphere ENA emissions from 2009 to 2017 (top, Mollweide projections centered on the upwind direction, i.e., the direction of the inflowing interstellar gas), showing the delayed response to the solar wind dynamic pressure (smoothed over two Carrington rotations, bottom panel). The shaded regions indicate a typical delay of ∼2–3 years for solar wind changes at 1 au to be recycled in 4.3 keV ENAs.
