The solar energy affects on the ionosphere is of a major concern and being investigated worldwide. As an ever changing-medium it difficult to precisely determine TEC, which also subjected seasonal variations. Conjugate stations allow excellent opportunities learn any asymmetric properties its phenomena. With these respects, this paper examine GPS derived TEC variations during vernal autumnal equinoxes period for year 2003 at polar conjugate stations. A month data (two weeks before after equinox onset) Scott Base station, Antarctica (SBA) Canadian Resolute Cornwallis Island station (RESO), Artic are analyzed. Results show that mean (VE) higher SBA than RESO by about 12.5% (AE) 12.6% with both having approximately similar total (VE+AE) 21 TECU. This preliminary investigation shows potential effects high latitudes towards better characterization ionospheric TEC.
