Summary
The analysis of event anisotropy with respect to the reaction plane has started at PHENIX.
Different reaction planes to extract anisotropy are compared  and the results are consistent.
v2 parameter of charged particle is saturated over 2 GeV/c.
v2 parameters of identified particles (p+/-,K+/-,p,pbar) are measured and the behavior of v2 above 2 GeV/c are different from the prediction by hydro-dynamical model.
