Forbush decreases and geomagnetic storms during a highly disturbed solar and interplanetary period, 4-10 September 2017
(AGU, 2019)Features and peculiarities of the cosmic ray intensity (CRI) and the geomagnetic activity, along with several solar plasma and interplanetary magnetic field, during the period 4–10 September 2017 are studied. The period ... -
Input parameter ranking for neural networks in a space weather regression problem
(In Proc. South African Forum for Artificial Intelligence Research (FAIR2019), 2019-12)Geomagnetic storms are multi-day events characterised by significant perturbations to the magnetic field of the Earth, driven by so-lar activity. Numerous efforts have been undertaken to utilise in-situ mea-surements of ... -
A multi-wavelength approach to solar energetic particle transport using remote sensing and in-situ observations
(North-West University (South Africa), 2022)Space weather (SWx) studies and the development of SWx prediction models have gained significant momentum in the last few years. Large SWx events have the potential to incapacitate technological infrastructure, both on ... -
Numerical investigation of solar energetic particle transport between the Sun, Earth, and Mars
(North-West University (South Africa), 2019)Solar energetic particles pose a danger to spacecraft electronics, and even more significantly, to a future spacecraft crew beyond the Earth’s magnetosphere. Given the current NASA and SpaceX interest in interplanetary ... -
Solar cycle variations and cosmic rays
(Elsevier, 2008)Cosmic rays are excellent indicators of the various solar cycle variations. Galactic and anomalous cosmic rays encounter an outward moving solar wind with cyclic magnetic-field fluctuations and turbulence, which constitute ... -
Sunspot detection and tracking using image processing techniques
(North-West University (South Africa), 2022)Over the past five decades, space weather forecasting has gained significant interest since mankind started exploring the solar system using highly developed technology. Power and communication systems are critical for ...
