We report the first evidence of atmospheric gravity waves (AGWs) generated in the F 2 region by high‐power HF heating and subauroral polarization streams. Data come from the CHAMP and GRACE spacecraft overflying the High‐frequency Active Auroral Research Program (HAARP) heating facility. These observations facilitate a new method of studying the ionosphere‐thermosphere coupling in a controlled fashion by using various HF‐heating regimes. They also reveal the subauroral F 2 region to be a significant source of substorm AGWs, in addition to the well‐known auroral E region.
