Abstract

We report the large-scale sidereal anisotropy of galactic cosmic-ray intensity in the multi-TeV region obtained with the Tibet III air shower array in the period from 1999 through 2003. The sidereal daily variation of cosmic rays observed with Tibet III clearly indicates the excess of relative intensity around 4 ∼ 7 hours local sidereal time, as well as the deficit around 12 hours local sidereal time. The amplitude of the excess is not significant when averaged over the declination, however it becomes larger and clearer as the declination of viewing direction moves toward the south. The maximum phase of the excess intensity shifts from ∼ 7 to ∼ 4 hours according to the declination moving from the northern hemisphere to the equatorial region. Furthermore.
