This was our final model which can measure the disturbances in the interplanetary magnetic field IMF. Geomagnetic storms are caused by the interaction of solar wind with Earth's magnetic field. The resulting disturbances in the geomagnetic field can wreak havoc on GPS (Global Positioning System) systems, satellite communication, electric power transmission, and more. These disturbances are measured by the Disturbance Storm-Time Index, or Dst.
