Observations of mass addition to the shocked solar wind of the Venusian ionosheathThe present investigation constitutes a continuation of a study conducted by Mihalov et al. (1980) concerning the heavy ion component in the plasma observations downstream from Venus, taking into account data obtained with the aid of the plasma analyzer experiment on the Pioneer Venus Orbiter (PVO). The current study is based on analyses of the first season of PVO orbits with apoapsis in the tail and provides clear evidence for the presence of heavy ions. It is found that a heavy ion component was added to the ionosheath flow for a prolonged period on June 8 and 11, 1979 while the spacecraft was downstream from the planet. The heavy ions are identified as oxygen ions O(+). Heavy ions are detected on most of the orbits in the first season or apoapsis tail passages.
