The data collection was satisfactory. The earths magnetism is a dynamic and complex field, the origin of which may be traced to terrestrial, atmospheric, planetary and interstellar phenomena. Accurate recording of the three component variations of the field is an important aspect of navigation, surveying, communication and fundamental research. Antarctica, a huge continent containing one of the poles of the earths magnetic field, becomes an ideal location to study geophysical phenomena occurring in the ionosphere and magnetosphere. Antarctica can be imagined as a screen where the dynamic processes occurring in the magnetosphere get projected through associated electric fields and currents, particle precipitation etc. This is so because magnetic lines of force act, to a high degree of accuracy, as equipotential lines of force for electric fields. As the polar region is at one end of the magnetic lines of force, magnetospheric electric field and particle motions are mapped over the Antarctic ionosphere.
