Auroral, Ionospheric and Ground Magnetic Signatures of Magnetopause Surface Modes

M. O. Archer, M. D. Hartinger, L. Rastaetter +6

Surface waves on Earth's magnetopause have a controlling effect upon global magnetospheric dynamics. Since spacecraft provide sparse in situ observation points, remote sensing thes…

Adaptations to a geomagnetic field interpolation method in Southern Africa

M. J. Heyns, S. I. Lotz, P. J. Cilliers +1

Space weather and its impact on infrastructure presents a clear risk in the modern era, as evidenced by the adverse effects of geomagnetically induced currents (GICs) in power netw…

Probabilistic Analysis of Power Network Susceptibility to GICs

M. J. Heyns, S. I. Lotz, C. T. Gaunt

As reliance on power networks has increased over the last century, the risk of damage from geomagnetically induced currents (GICs) has become a concern to utilities. The current st…

Data Driven Transfer Functions and Transmission Network Parameters for GIC Modelling

M. J. Heyns, C. T. Gaunt, S. I. Lotz +1

Typical geomagnetically induced current (GIC) modelling assumes the induced quasi-DC current at a node in the transmission network is linearly related to the local geoelectric fiel…

Frequency Components of Geomagnetically Induced Currents for Power System Modelling

D. T. O. Oyedokun, M. J. Heyns, P. J. Cilliers +1

Geomagnetically induced currents (GICs) in power systems are conventionally modelled as direct currents, based on their commonly described quasi-DC nature. For more representative…

dSECS: Including Variometers in Geomagnetic Field Interpolation

M. J. Heyns, S. I. Lotz, C. T. Gaunt

One of the best tools we have in geophysical modelling is the ability to interpolate the horizontal geomagnetic field at the surface of the Earth. This is especially useful in regi…
