Abstract:

A system, method and computer-readable medium for mapping magnetic activity for a current linking a planet's space environment to an ionosphere of the planet are disclosed. Magnetic field measurements of the current are obtained from a plurality of satellites orbiting the planet. A residual magnetic field is determined from the obtained magnetic field measurements. The determined residual magnetic field is arranged to create a time series for a selected location of a planet-centered coordinate system. The magnetic activity is mapped using the created time series for the selected location.
