Scientific paper

The anisotropy of energetic ions due to solar wind convection is investigated at Comet Halley on the basis of data obtained by EPONA aboard Giotto. A simple method is introduced to determine the ion velocity from the counting rates detected in two sectors with different viewing angles relative to the sun. The calculated ion velocities imply that the cometary ions observed up to 8 million km from the nucleus are unlikely to be protons and most probably comprised oxygen (or water group) ions. Consequences accruing to the appearance of heavy ions at large distances from the nucleus are discussed.
