Abstract

It seems conceivable that, in 2002-2004,Voyager-1 was still inside the termination shock, but its magnetic field line had intersected the shock between V-1 and the Sun. This may well occur if the field line intersect the shock multiple times, which can occur for a number of plausible reasons. We discuss this of multiple intersection in the light of new findings of V-1 since crossing the shock in December 2004. We address the effects of such multiple intersection on the energy spectra. and stress that the shock will not produce a uniform power-law everywhere. Instead, a two-population spectrum, similar to that observed by Voyager-1, can be expected if flirting field lines cross and recross the shock. The two-population spectra observed by V-1 is interpreted as a signature of acceleration at different sites.
