Abstract

Although the moon has basically an unmagnetized body, there are number of magnetic anomalies and presence of mini-magnetosphere is suggested over the anomalies. The LRS/WFC onboard KAGUYA, a Japanese lunar orbiter, frequently observed intense wave activities below several kHz over these magnetic anomalies at altitude range below 100 km. It was found that the spatial distribution of plasma wave clearly corresponds to the magnetic anomalies and also depends on the solar wind parameters. We also introduce characteristics of the plasma waves and relationship between wave and particle features.
