Summary

Radial profiles of heavy cometary ions at large solarzenith angles were obtained with the BD-3 plasma detector. The relatively sharp (thickness ~8000 km) boundary at ~1.5 105 km of the region where cometary ions dominate, may result from a violation of the frozen-in condition of solar wind protons along the field lines. The density of the heavy ions mantle varies approximately as R −2 . A large-scale density enhancement was observed during the inbound crossing at 65,000–25,000 km on March 6, 1986. Many small-scale (250-1,000 km) density enhancements were observed. A local maximum of ~4 103 cm−3 at ≈1.2104km was observed on inbound and on outbound trajectories of Vega-1 which shows the permanent existence of this pile-up feature. Data on the bow shock crossing and on the mantle density distribution are discussed and compared with the data of other experiments.
