AB: The magnetometer and electron reflectometer experiment on the Lunar Prospector spacecraft have detected low frequency waves at ~ 1 Hz in the vicity of the Moon. These narrow band features are imposed on a broad spectrum of noise observed by Lunar Prospector when it is sunward of the moon. The polarization properties of these waves are analyzed using the three-dimensional covariance matrix method. We find that these waves are left circularly polarized. We present a detailed analysis of the magnetic field and charged particle observations. We attempt to identify the mode of these fluctuations and examine whether these waves are due to the ion beams associated with the wake, or pick-up ions, or the energetic electrons associated with the Moon.
