We analyze the features of energetic electron precipitation (with the maximum energy E ≥ 150 keV) from the Earth’s radiation belt into a magnetically conjugate region of the ionosphere (relative to the Sura facility) during modification of the ionospheric F2 region by high-power HF O-mode radio waves in the regime of their continuous radiation. Precipitation was recorded by the DEMETER satellite at an altitude of 660 km. Criteria for observation of artificial precipitation were determined, and it was found that the precipitation area stretches to a distance of up to 2200 km along the geomagnetic meridian. The transverse size of the area exceeds 500 km. Comparison between the nature of precipitation in the magnetically conjugate region and precipitation directly in the region disturbed by high-power HF radio waves of the Sura facility is performed.
