A measurement of the cosmic ray anisotropy on the arrival directions of positrons and electrons has been performed in galactic coordinates by the Alpha Magnetic Spectrometer onboard the International Space Station. The analysis is based on the first 10 years of data taking. Results are consistent with isotropy and upper limits on the dipole amplitude (𝛿) at the 95% C.I. have been established. In particular, for energies above 16 GeV limits of 𝛿 < 1.50% and 𝛿 < 0.33% are obtained for positrons and electrons respectively.
