We assemble a sample of 3417 Early Type Galaxies observed both in the optical (\\textit{SDSS}-DR8) and the UV (\\textit{GALEX}-GR6). The galaxies in our sample can be classified according to their position in the colour-colour diagram as UV weak or red sequence galaxies ($\\sim 48\\%$), UV strong or UVX galaxies ($\\sim 9\\%$), and recent star forming galaxies ($\\sim 43\\%$).
