We present a relation that links the flux, the distance arid the decay index of the GRB afterglows. We actualized it in X-ray using BeppoSAX, XMM-Newton, Chandra and SWIFT observations. We discuss the similar behaviour found recently at optical wavelengths using SWIFT afterglow data. We present evidences that this relation can be used to estimate the source distance as well as the optical extinction.
