Results are shown from an experimentalcampaign where satellite scintillation was observed at three sites at highlatitudes and, simultaneously, the F region plasma flow was measured by thenearby EISCAT incoherent scatter radar. The anisotropy parameters offield-aligned irregularities are determined from amplitude scintillation using amethod based on the variance of the relative logarithmic amplitude. Theorientation of the anisotropy in a plane perpendicular to the geomagnetic fieldis compared with the direction of F region plasma flow. The results indicatethat in most cases a good agreement between the two directions is obtained.  <b>Key words: </b>Ionosphere (auroralionosphere; ionospheric irregularities
