**The running BFKL equation gives rise to a series of moving poles in the complex j-plane. Corresponding eigenfunctions (color dipole cross sections) are the oscillating functions of the color dipole size r. The first nodes for all sub-leading solutions (color dipole cross sections) accumulate at ri ~ 0.1 fm. Therefore the processes dominated by the dipole sizes r ~ ***ri *are free of sub-leading BFKL corrections. A practically important example the leptoproduction of charm. In a wide range of *Q*^{2} the calculated F|^{c}(z, *Q*^{2}) is exhausted by the leading BFKL pole and gives a perfect description of the experimental data.
