ABSTRACT
The possible effect is discussed on the Schumann resonance records of the giant γ -ray flare from Sagittarius constellation (SGR 1806-20). We show that the dayside ionosphere modification is able to cause noticeable abrupt change in the power spectra global electromagnetic resonance. Spectral modifications gradually fade in time, so that usual spectra patterns are recovered in some time after the burst. A technique is proposed for measurements, which emphasizes the gamma burst effect.
