Rosetta IES observations of solar wind ions on 30 October 2014 from 2200 to 2300 UT. This energy-angle plot shows the arrival anode of solar wind and cometary ion fluxes. The directions to the Sun and comet are shown. Solar wind H⁺ and He²⁺ are propagating at the same speed of 370 km s^-1 (and therefore He²⁺ appears at twice the H⁺ energy per charge in the IES electrostatic analyzer). The solar wind is not propagating radially away from the Sun because of cometary ion pickup. The extent and direction of the deflection depend on the comet outgassing rate and the orientation of the solar wind magnetic field. The existence of He⁺ is further evidence of the interaction with the comet coma. It is created by charge exchange of solar wind He²⁺ with cometary neutrals.
