A1 Hayakawa, Masashi T1 MODEL OF DISTURBANCE OF GLOBAL ELECTROMAGNETIC RESONANCE DURING EXTRA-GALACTIC GAMMA RAY FLARE ON DECEMBER 27, 2004 JF Telecommunications and Radio Engineering JO TRE YR 2011 FD 2011-03-04 VO 70 IS 1 SP 73 OP 85 K1 the Schumann resonance K1 gamma-burst K1 the lower ionosphere AB 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. PB Begell House LK https://www.dl.begellhouse.com/journals/0632a9d54950b268,386eb8c7104dbedb,6cf3eb6f5bfc32d0.html
