The planetary magnetic fields in the solar system deflect/reflect solar wind at bow shocks in front of their magnetospheres, protecting the planets from direct solar wind bombardment. Indirect evidences suggest that the sporadic magnetic anomalies on the Moon, i.e., the small-scale magnetic fields, do the same, protecting the lunar surface below and even modifying the chemical/optical properties there. It is, however, still unclear how these anomalies interact with solar wind because of lack of in-situ observations. Two key remotely-sensed symptoms, i.e., the lunar reflected ions and the associated ~1Hz waves, are organized in a particular coordinate system here to diagnose the solar wind interaction. We show that particles are reflected around the specular direction above the lunar surface, hinting an electric-field effect in the reflection, and that whistler wings form, suggesting a distinct solar wind interaction scenario to that of a giant planetary field.
