New results of the DMSP satellite and HAARP digisonde observations during HF heating at the High‐Frequency Active Auroral Program (HAARP) facility are described. For the first time, the DMSP satellites detected significant ion outflows associated with 10–30% density enhancements in the topside ionosphere above the heated region near the magnetic zenith. In addition, coincident high‐cadence skymaps from the HAARP digisonde reveal field‐aligned upward plasma flows inside the F ‐peak region. The SAMI2 2 model calculations are in fair agreement with the observations.
