The STAR Forward TPCs (FTPCs) extend the STAR acceptance for charged particles into the region 2.5 2) where in the case of v_4 a signal is seen in the STAR TPC. With the available statistics for the FTPCs we give an upper limit for these harmonics, since the results agree with zero within the errors. However, the falloff of v_4 from mid-rapidity to forward-rapidities appears to be faster than for v_2.[1] B.B. Back. Phys. Rev. Lett. 89, 222301 (2002)
