A new wave ULF-index has been applied for analyzing daytime wave activity in ultra low frequency range (ULF, namely, 2-6 mHz) during 19 strong magnetic storm (-150 nT < Dstmin < -100 nT). It is found that at autoral latitudes the most intensive morning-noon geomagnetic pulsations are observed in the main phase of the magnetic storms. It is shown the magnetic storm sudden commencement, characterizing by the solar wind density enhancement and the solar wind speed jump, is accompanied by the sharp… CONTINUE READING
