Superkamiokande atmospheric neutrino data for 535 days are analyzed in the framework of three flavor oscillations with mass hierarchy. It is shown that the best fit point is very close to the pure maximal ν_μν_τ case and Δ m^2 ≃ 7×10^-3 eV^2. The allowed region at 90 baseline experiments are briefly discussed.
