AB: Images of charge-exchanged neutrals from ion outflow during a period of substorm recovery are supported by simultaneous in situ ion outflow measurements and images of the auroral oval. From this combination of remote sensing and in situ measurements, the ion outflow is shown to consist of ion conics that likely increase in energy as the conics rise out of the Earth's ionosphere. Above about 1.6 Earth Radii, the conic thermal energy is greater than 10 eV while at about 0.7 Earth Radii, it is below this value. This outflow occurs over the entire dayside auroral oval at high latitudes, even in the vicinity of the cusp, where the auroral emissions are relatively weak. Outflow on the nightside may be weaker than on the dayside and/or may have a different energy-altitude dependence.
