  We extend our study of bottomonium spectral functions in the quark-gluon
plasma to nonzero momentum. We use lattice QCD simulations with two flavours of
light quark on highly anisotropic lattices and treat the bottom quark with
nonrelativistic QCD (NRQCD). We focus on S wave (Upsilon and eta_b) channels
and consider nonrelativistic velocities, v/c < 0.2. A comparison with
predictions from effective field theory is made.
