The H2O outburst in Orion KL had been observed by the VLBI technique in 1979–1983. The line profile is asymmetrical. The flux density and line width are variable and correspond to a partially saturated maser. The outburst region had a compact and a less compact one whose sizes are equal to 0.3 and 2.5 a.u. respectively. The fine structure of the profile corresponds to knots whose size is smaller 0.2 a.u. The brightness temperature of the region, Tb ≃ 1017K, implies a high emission directivity
