We investigate dynamical plasma screening effects on a heavy-quark--antiquark pair traversing a quark-gluon plasma. The screened potential created by a test charge (heavy quark) moving in the plasma medium is calculated in the test charge frame by solving the transport equation for a collisionless ultrarelativistic plasma interacting via Abelian gauge field. It is shown that the screened potential becomes strongly anisotropic as the velocity of the plasma medium increases. Possible implications of this effect for charmonium production in relativistic heavy-ion collisions are discussed.
