Description:
Pioneer Venus Orbiter magnetometry and plasma analysis data are presently used to investigate the draped-field Venus magnetotail, with a view to ascertaining the magnetic field and plasma conditions within the various regions of the tail and their dependence on the IMF's orientation. It is found that the distribution of plasma within the magnetotail is highly asymmetric, and controlled by IMF orientation. The magnetotail-ionosheath interface downstream of the Venus hemisphere over which the solar wind motional electric field is outward is very broad, and resembles a slow mode expansion fan with slowly decreasing field strength and gradually increasing plasma density.
