Evidence for unusually high densities of plasma in the Venusian ionosheath

An unusual occurrence was recorded by Pioneer Venus Orbiter (PVO) in the Venusian ionosheath on November 10-11, 1981 (orbit 1071): more than an order of magnitude higher densities of ions and electrons were observed than have ever been measured by PVO before then or since. This region of enhanced densities covered an extended region in the dayside ionosheath. The purpose of this paper is to briefly present our analysis of these unique observations.
