Electrostatic Waves and Electron Heating Observed Over Lunar Crustal Magnetic Anomalies

Above lunar crustal magnetic anomalies, large fractions of solar wind electrons and ions can be scattered stream back towards the flow, leading to a number interesting effects such as electrostatic instabilities waves. These structures also interact with background plasma, resulting in electron heating scattering. We study waves observed over anomalies by analyzing data from Acceleration, Reconnection, Turbulence, Electrodynamics Moon's Interaction Sun (ARTEMIS) spacecraft. Based on analysis two flybys 2011 2013, we find that two-stream instability (ETSI) cyclotron drift (ECDI) may play an important role driving ECDI, along modified (MTSI), provide mechanisms responsible for substantial isotropic anomalies.
