An all-sky catalog of 18,020 disc-like galaxies is created to study cosmic streamings on a scale of z < 0.1. The galaxies are selected from the Extended Source Catalog of the Two Micron All-Sky Survey (XSC 2MASS) basing on their 2MASS axial ratio a/b > 3. The "2MASS-selected Flat Galaxy Catalog" (2MFGC) contains data on galaxy magnitudes in the J, H, Ks bands, axial ratio, positional angle and other basic galaxy parameters.
We study the peculiar velocity field traced by 2,700 spiral galaxies in the 2MFGC with known velocities and rotation amplitudes. Distances to the galaxies are estimated from the J-band Tully-Fisher relation having a scatter of 0.45 mag.
The bulk flow of the 2MFGC sample in the CMB frame is (199+-37) km/s, toward l = (290+-11) degr, b = (+1+-9) degr. The dipole motion amplitude tends to decrease with depth, showing the expected convergence to the CMB frame. We suggest that about 60% of the bulk flow within z = 0.03 is caused by external attractors like the Shapley Concentration of rich clusters.
