The OPERA experiment was designed to perform the first detection of v(mu) -> v(T) neutrino oscillations in a direct appearance mode. We present the analysis results of the 2008-2009 statistics corresponding to 4.88 x 10 19 p.o.t. In this sample, one v(T) candidate event has been observed in the T -> h channel. The statistical significance of this observation is estimated to be 95%.
