Geomagnetic Disturbances

Abstract

The Sun s changing magnetic field interacts with the Earth s magnetosphere causing geomagnetic activity. The fundamental questions we seek to understand are the origin of solar activity seen at the Sun s surface, how the photospheric magnetic field is expressed in the corona and interplanetary medium, and how, ultimately, the variations of the solar field affect the terrestrial environment. Our goal is to develop tools for reliably forecasting, from photospheric observations, the solar events and solar wind conditions that result in the geomagnetic disturbances that impact human activities on and near Earth.
