The elliptic flow v2 of thermal photons at midrapidity in Au+Au collisions at sqrt(SN N) = 200 GeV is predicted, based on three-dimensional ideal hydrodynamics. Because of the interplay between the asymmetry and the strength of the transverse flow, the thermal photon v2 reaches a maximum at pT ∼ 2 GeV/ c and the pT-integrated v2 reaches a maximum at about 50% centrality. The pT-integrated v2 is very sensitive to the lower limit of the integral but not sensitive to the upper limit due to the rapid decrease in the spectrum of the tran...
