Abstract: Observations of ionospheric scintillation in polar region are presented in this paper. Some ionospheric scintillation characteristics were obtained when the sun activity was at low level using the data of Sodankyla and Tromso from March 2004 to September 2008. As the sun activity decreases, the scintillation occurrence reduces evidently. Due to the different producing mechanism, different to the low latitude region, among all the scintillations, most are phase scintillations. Polar scintillation is not limited to the local nighttime and occurs in all seasons. And, polar scintillation is strongly dependent on geomagnetic activity.
