The data has been synthesized against similar observations made in two observatories nearest and equidistant from a point in northern hemisphere which is conjugate to Maitri in southern hemisphere. The Indian Antarctic stations Dakshin Gangotri (DG) and Maitri (MAI), during magnetically quiet times occupy a sub- auroral position i.e. they lie just equatorward of what is known as the auroral zone. The auroral zone defines a narrow band of latitudes lying between about 60?-70? magnetic latitudes, where the optical atmospheric phenomenon of aurora occurs most frequently on a daily basis. Few space phenomena are linked as closely as aurora and variations in the geomagnetic field. It is the configuration of the geomagnetic field which decides the latitude at which auroral displays occur and it is the energy state of the geomagnetic field which decides the form, fine structure and colours which auroral displays will take.
