Solar variability detected by spectral analysis of Earth and satellite observations during various solar cycles

Dr Pieter Kotze, from SANSA will present the NASSP seminar with a talk entitled, "Solar variability detected by spectral analysis of Earth and satellite observations during various solar cycles"

In this presentation it will be shown how the Sun’s magnetic field varies during a solar cycle and the influence this variability has on the heliosphere. Various spectral analysis techniques will be used to reveal the changing pattern of certain periodicities in particle and geomagnetic activities as observed by both satellite and ground observations, e.g. the 27–day rotation period. This information can be used to detect the axisymmetric solar magnetic field during the prolonged and unusual minimum of solar cycle 23-24.
