This paper presents the results of an experiment on the possible reaction of the geomagnetic field to the modification of the ionosphere by powerful radio emission from the SURA facility. The measurements were carried out at two remote points tens of kilometers to the north and south of the SURA. Pulsations in the Pc 3–5 range were detected during the SURA facility operation at both points, and their waveform and spectra were close to identity. An interpretation of the observed phenomenon on the basis of the ionospheric RF heating mechanism for the excitation of the so-called ionospheric feedback instability is given.
