Anisotropic patterns in the azimuthal distribution of D0, D+ and D* mesons were studied with the ALICE detector in Pb-Pb collisions at the LHC, at a
centre-of-mass energy sqrt(s_NN)=2.76 TeV per nucleon--nucleon collision.
In particular, in the centrality class 30-50\%, the second harmonic Fourier coefficient v2 (indicated as elliptic flow) was measured as a function of the D meson transverse momentum.
D meson v2 is observed to be larger than zero at 3 sigma level in the range 2<pt<6Gev/c.
