The measurements of the reduced cross sections for e+p deep inelastic 
scattering at high inelasticities y for three different centre-of-mass 
energies, 318, 251 and 225 GeV have been extended to lower momentum 
transfered squared, Q^2. The analysis of satellite vertex events allows to 
extend the cross section measurement at high y down to Q^2 = 5 GeV^2, 
substantially lower than the previously published cross section 
measurements from which the longitudinal structure function, FL, was
extracted.
