Description
The cosmic-ray anisotropy is now used to help unveil nearby cosmic-ray accelerators and their local propagation environment. The LHAASO-WCDA experiment is composed of three water ponds. It covers a total detection area of 87000 m^2, which makes it an ideal detector for measuring the cosmic-ray anisotropy from hundreds of GeV to ∼PeV. In this talk, we present the measurements of the cosmic-ray anisotropy using three years of WCDA data. We extended our measurement to the lower energy, about 600 GeV. We find a significant energy dependence of the dipole component of the sidereal-time anisotropy below several TeV. Meanwhile, we also find the remarkable influence of solar activities on the solar-time anisotropy at sub-TeV.
