• The observation of parallel ion velocity in the near‐lunar wake approximately equal to external solar wind velocity can be explained within uncertainties by an analytic electrostatic expansion model. The one‐dimensional model frequently used is inadequate because it does not account for the moon's spherical shape. However, application of a more recent generalization to three dimensions of the solution along characteristics predicts higher velocities and is probably sufficient to account for the SARA observations on the Chandrayaan‐1 spacecraft. Key PointsObserved near lunar ion velocity is explicable by electrostatic acceleration.A self‐consistent 3‐D theory is required and available.Direct calculation shows agreement probably within uncertainty.
