It is shown that the CKMT model for the nucleon structure function F2 gives a good description of the recent HERA data at low and moderate Q2. A fit to the same data, obtained with a modified version of the model in which a logarithmic dependence on Q2 has been included, is also presented. For moderate values of Q2, in the current available range of x, the first parametrization leads to a better description of the data.
