We present observations of interstellar pickup hydrogen and helium in the solar wind which show large, highly‐correlated fluctuations in flux which are not correlated significantly with the solar‐wind hydrogen flux. The correlation of the fluctuations in the two species implies that the fluctuations are caused by transport after ionization. The lack of correlation with the thermal flux means they are not caused by compressions of the wind. We present a new model which can naturally produce the observed fluctuations in the pickup ions.
