N2 - A parametrization of the real photon structure function F2γ in the low Q2, low x region is formulated. It includes both the vector meson dominance (VMD) and the QCD components, the latter suitably extrapolated to the low Q2 region and based on arbitrary parton distributions in the photon. The parametrization used together with the Gluck, Reya, and Vogt (GRV) and Gluck, Reya, and Schienbein (GRS) parton densities describes reasonably well the existing high energy data on F2γ, σγγ, and the low Q2 data on σγ*γ. Predictions for σγγand for σγ*γ for energies which may become accessible in future linear colliders are also given.
