Determination of the intercept of the BFKL pomeron is one of the pressing issues in the high energy physics. Earlier we have shown that, at the dipole size r=rΔ=(0.1-0.2)f, the dipole cross section σ(x,r) which is a solution of the generalized BFKL equation, exhibits a precocious asymptotic behavior σ(x,r)∝ (1 x)Δ. In this paper we discuss how measuring Fₗ(x,Q²) and ∂ Fₜ(x,Q²)/∂ Q² at Q²= (10-40)GeV² and Q²=(2-10)GeV², respectively, one can probe σ(x,rΔ) and directly determine the intercept Δ of the BFKL pomeron in the HERA experiments.
