Abstract

The amplitude and phase of the first harmonic of the sidereal anisotropy of cosmic rays at Ē ⁰ = 2-10 ¹⁴ eV have been measured by the EAS-TOP experiment (Campo Imperatore, 2005 m a.s.l., LNGS, Italy) and are respectively (at the equatorial plane): A _sid = (3.73±0.57)·10 ^-4 ; φ _sid = 1.82±0.49 h lst, with significance 6.5 s.d. The result is supported by different consistency checks. From the comparison with lower energy data, it follows that the amplitude and the phase of the cosmic ray anisotropy are constant over the energy range 10 ¹² - 2·10 ¹⁴ eV. This implies at these energies a constant influence of the local interstellar medium on the propagation of cosmic rays.
