Upstream electron oscillations and ion overshoot at an interplanetary shock wave

During the passage of a large interplanetary shock on 13 October 1981, the ISEE-1 and -2 spacecraft were in the solar wind outside of the upstream region of the bow shock. The high time resolution data of the University of California particle instruments enable us to pinpoint the expected electron spike as occurring just before the magnetic ramp. In addition, two features that occur at this shock have not been observed before: 1) electron oscillations associated with low frequency waves upstream of the shock and 2) sharp 'overshoot' (approx.1 sec) in the ion fluxes that occur right after the magnetic ramp. This interplanetary shock exhibits many of the same characteristics that are observed at the Earth's bow shock.
