Scientific paper

The first observations of interplanetary scintillations with EISCAT facilities are reported. The large separation of the two receiving antennas (268 km) provides an excellent range of baselines and allows an accurate determination of the spatial properties of the drifting pattern. This permits the use of a new estimator of the mean velocity which is valid for any strength of scattering and is independent of the existence of turbulence in the velocity field. The results obtained are consistent with earlier work and show two particularly interesting features. The density fluctuations are anisotropic with an axial ratio of about 2. However the major axis can deviate as much as 20 deg from the radial direction. A two-dimensional random velocity field is observed with an axial ratio of 1.3 to 3.0 aligned approximately radially. The analysis demonstrates that reliable solar wind measurements can be conducted with EISCAT antennas at solar elongation between 15 and 70 solar radii.
