We examine the Voyager 1 (V1) and Voyager 2 (V2) intensity vs. time profiles in several energy bands of low-energy particle populations during the period 2005 through early 2007. There appear to be a set of propagating structures with ~1 year duration that appear first at V2, which is upwind of the solar wind termination shock, and then ~115 days later at V1 in the heliosheath. We will discuss these observations in the context of the source and transport of the termination shock particles and anomalous cosmic rays.
