Abstract. This work is the first step in a systematic effort to understand
and predict the different components of the UV (912 °A - 3000 °A) radiation
field over the entire sky. We have developed a model to predict the ISRF in the
UV within a few hundred parsecs of the Sun using the Hipparcos star catalog.
We have checked the model through a comparison with the observations of the
Belgian/UK UV sky survey telescope (S2/68) on the ESRO TD-1 satellite.
