The influence of the interplanetary magnetic field on the bow shock near Venus
Abstract
Measurements made by Pioneer Venus and by Venera 9 and 10 spacecraft were used to study the dependence of the position of a point at which the bowshock front is passed from the direction of the interplanetary field component perpendicular to a vector of the solar wind velocity. The planetocentric distance to the bow shock corresponding to each crossing was plotted to the theta (eta beta) value. In each case, the IMF value was determined by averaging over 5 min interval closest to the front crossing moments. The found dependence shows that the distance from the planet center to the bow shock of Venus near the terminator plane grows for the increase and reduces for the decrease of the IMF value. When the IMF value varies from 5 gamma to 15 gamma the distance is the terminator plane.
