  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 $r_1\sim 0.1
fm$. Therefore the processes dominated by the dipole sizes $r\sim r_1$ are free
of sub-leading BFKL corrections. A practically important example - the
leptoproduction of charm. In a wide range of $Q^2$ the calculated
$F_2^{cc}(x,Q^2)$ is exhausted by the leading BFKL pole and gives a perfect
description of the experimental data.
