摘要：
The sharp drop in fluxes of the termination shock particles observed by Voyager 1 in the inner heliosheath at distance of about 122 au from the Sun can be explained by factors, which are not related to the heliopause crossing as is now commonly believed. It is shown that the region of the heliosheath occupied by the current sheet can be considered as a reservoir for suprathermal charged particles accelerated at the termination shock. When a spacecraft crosses the boundary of this region in the latitudinal direction, fluxes of the suprathermal particles can vary by several orders of magnitude.
