We report the results of applying the 2MASS Tully-Fisher (TF) relations tostudy the galaxy bulk flows. For 1141 all-sky distributed flat RFGC galaxies weconstruct J, H, K_s TF relations and find that Kron $J_{fe}$ magnitudes showthe smallest dispersion on the TF diagram. For the sample of 971 RFGC galaxieswith V_{3K} < 18000 km/s we find a dispersion $\sigma_{TF}=0.42^m$ and anamplitude of bulk flow V= 199 +/-61 km/s, directed towards l=301 degr +/-18degr, b=-2 degr +/-15 degr. Our determination of low-amplitude coherent flow isin good agreement with a set of recent data derived from EFAR, PSCz, SCI/SCIIsamples. The resultant two- dimensional smoothed peculiar velocity field traceswell the large-scale density variations in the galaxy distributions. Theregions of large positive peculiar velocities lie in the direction of the GreatAttractor and Shapley concentration. A significant negative peculiar velocityis seen in the direction of Bootes and in the direction of the Local void. Asmall positive peculiar velocity (100 -- 150 km/s) is seen towards thePisces-Perseus supercluster, as well as the Hercules - Coma - Corona Borealissupercluster regions.Comment: 10 pages, 5 figures.
