In this paper we determine the dipole in the distance redshift relation from the Pantheon+ data. We find that, while its amplitude roughly agrees with the dipole found in the cosmic microwave background which is attributed to the motion of the solar system with respect to the cosmic rest frame, the direction is different with a significance of slightly more than 3. While the amplitude depends on the lower redshift cutoff, the direction is quite stable. For redshift cuts of order z_(cut) ≃0.05 and higher, the dipole is no longer detected with high statistical significance. An important r\^ole seems to be played by the redshift corrections for peculiar velocities.
