Abstract
Ions of ionospheric origin (mostly O+ and He+) form a significant component of the plasma in the Earth's magnetosphere. These ions are extracted from the high-latitude topside ionosphere by a series of processes which heat the ions both parallel and perpendicular to the geomagnetic field. The amount of plasma outflow is correlated with geomagnetic and solar activity. However, previous studies of ion outflow in the ionosphere have relied on F10.7 as a proxy for solar activity because no routine solar EUV flux measurements were available. The simultaneous availability of solar EUV flux measurements and ion outflow data from the Fast Auroral Snapsho T Explorer (FAST) during the rising phase of the solar cycle allows us to make definitive measurements of the dependence of ion outflow at auroral latitudes on solar EUV irradiance.
