Abstract

The north-south asymmetry of galactic cosmic ray fluxes has been measured in the PAMELA experiment during the time period 2010-2014. Within this period the solar magnetic field was reversed. This gave an opportunity to follow the variation of the asymmetry effect. The variation of high energy cosmic ray flux ratio for particles arriving from North and South has been measured with aid of the PAMELA calorimeter. It was obtained that the value of this ratio changed during the time of reversal. Thus the obtained results confirm the conclusion about connection of northsouth particle flux asymmetry with the solar magnetic field.
