Scientific paper

The burstlike enhancements of energetic O(+) ions observed 28 million km upstream of Comet Halley by the energetic particle instruments on the ICE spacecraft in March 1986 and reported by Scarf et al. (1986), Wenzel et al. (1986), and Sanderson et al. (1986) are considered theoretically. It is shown that O atoms produced by two-step photodissociation of CO2, but not by dissociation of H2O and CO could attain the speed required to reach the ICE at the observation point, but that the theoretically estimated flux of 0.02 80-160-keV ions/sq cm sec at the spacecraft is much smaller than the observed flux of about 100 ions/sq cm sec. It is suggested that the ions observed may not be of cometary origin.
