Small-scale anisotropy in the solar wind

Abstract:

We investigate small-scale anisotropy of the interplanetary magnetic field (IMF) fluctuations in the solar wind by using high resolution Cluster data in two different periods. A minimum variance analysis is performed in order to study the anisotropy at several temporal scales. The eigenvalues λ1, λ2, λ3 of the minimum variance matrix and the angle θ between the mean magnetic field and the minimum variance direction are computed. Results from the statistical analysis show significant changes close to the ion cyclotron frequency.
