Illustration of the solar wind interaction with the lunar magnetic anomaly. The blue lines indicate the flow of solar wind protons that are subsequently modified by the interaction with the magnetic anomaly resulting in a deflection and thereby reaching the enhanced region without a change in velocity, b deceleration inside the magnetic anomaly due to the potential structure of +150V and reach inside magnetic anomaly, or c heating and reflection to space before reaching the lunar surface [from Futaana et al. (2013)]
