AB: 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 and then ~115 days later at V1. During this period V1 is continually in the heliosheath whereas V2 is upstream of the solar wind termination shock. We will discuss these observations in the context of the source and transport of termination shock particles and anomalous cosmic rays. This work was supported by NASA under contract NAS7-03001.
