Abstract
We have performed numerical simulations of the interplanetary transpor t of solar cosmic rays. The particles form a coherent pulse within sim ilar to 0.01 AU after their injection. The gradual decrease of a pulse 's speed and anisotropy can be understood in terms of an equilibrium b etween pitch-angle scattering and focusing. The results should be usef ul for estimating times of particle injection.
