Quasi-periodic changes of three dimensional solar anisotropy of galactic cosmic rays for 1965-2014

R. Modzelewska, M. V. Alania

We study features of the 3D anisotropy of galactic cosmic rays (GCR) for 1965-2014. We analyze the 27-day variations of the 2D GCR anisotropy in the ecliptic plane, and the north-s…
