Abstract We show that the assumption of type II seesaw mechanism for small neutrino masses coupled with b – τ mass unification in a minimal SUSY SO (10) model leads not only to a natural understanding of large atmospheric mixing angle ( θ 23 ) among neutrinos, as recently noted, but also to large solar angle ( θ 12 ) and a small θ 13 ≡ U e 3 as required to fit observations. No additional symmetries are required to obtain large neutrino mixings. The proposed long baseline neutrino experiments will provide a crucial test of this model since it predicts U e 3 ≃0.16.
