Correlation study of geomagnetic sudden storm commencements (SSCs)

In this paper we evaluate the correlation of sudden storm commencement (SSC) measurements due to solar activity. These measured waveforms usually indicate the arrival of a geomagnetic storm at the Earth. This paper presents evidence of the correlation of the arrival of the magnetic fields at many diverse locations on the Earth and also shows a correlation with the particle momentum flux measured in space that compresses the Earth's magnetic field on the Sun-facing side, and creates the SSC magnetic field that is observed on the Earth's surface.
