Description: Usikov Institute for Radio-Physics and Electronics, National Academy of Sciences of the Ukraine, 12, Acad. Proskura Street, Kharkov 61085, Ukraine. We describe the ionospheric modification by the SGR 1806-20 gamma flare (27 December 2004) seen in the global electromagnetic (Schumann) resonance. The gamma rays lowered the ionosphere over the dayside of the globe and modified the Schumann resonance spectra. We present the extremely low frequency (ELF) data monitored at the Moshiri observatory, Japan (44.365° N, 142.24° E). Records are compared with the expected modifications, which facilitate detection of the simultaneous abrupt change in the dynamic resonance pattern of the experimental record. The gamma flare modified the current of the global electric circuit and thus caused the parametric ELF transient. Model results are compared with observations enabling evaluation of changes in the global electric circuit.
