AB: SuperDARN radars are well suited to study interhemispheric features related to ionosphere-magnetosphere coupling. The behaviour and limits of magnetic conjugacy of auroral zones is not yet fully understood. In this study, we have analysed the occurrence, line of sight velocities and spectral width of near range echoes (60ø to 65ø of magnetic latitude) for meridional beams of the Hankasalmi and Kerguelen radars, respectively in the northern and southern hemisphere for the whole year 2001. Several events exhibiting a high level of conjugacy for all radar parameters are presented as well as the general features.
