Abstract

The large-scale anisotropy (or the so-called star-diurnal wave) has been studied in the frame of research carrying out in space with the PAMELA instrument. It was studied during the time period covering 2006-2014 for the Southern and Northern hemispheres simultaneously. The cosmic ray intensity distribution was constructed in the equatorial coordinate system and the anisotropy was obtained. For a dipole approximation its amplitude and phase have been measured for cosmic ray particles with energies 1-20 TeV/n. This result well known from ground based measurements has been obtained in space for the first time.
