Changes of the first Schumann resonance frequency during relativistic solar proton precipitation in the 6 November 1997 event
International audience The variations of the first mode of Schumann resonance are analyzed using data from Kola peninsula stations during the solar proton event of 6 November 1997. On this day the intensive flux of energetic protons on GOES-8 and the 10% increase of the count rate of the neutron mon...
