| Abstract: | A distribution of matter up to 100 h
-1 Mpc could be obtained from the large-scale galaxy peculiar motions. The best picture of such motion is given for today by
two galaxy catalogs, namely MarkIII and RFGC. We compare their velocity fields and show they are very similar and have not
only practically the same multipole structure but also a corresponding small-scale motions . We estimate a mean radial component
of this small-scale motion as 500–700 kms. An additional comparison of distances to common galaxies is made.
