Lunar nightside electron fluxes.
Abstract
Studies of particle fluxes at the lunar surface with the Apollo 14 ALSEP/CPLEE particle spectrometer during lunar night periods have shown three distinct types of electron flux events. One of these is shown to originate at the earth's bow shock, but the remaining two are shown to arise most likely as a result of local solar wind-lunar interactions. The flux events had mean electron energies of a few hundred electron volts and total fluxes of 10 to the 5th to 10 to the 7th electrons/sq cm-sec. These fluxes are a possible source of the large negative lunar surface potentials observed by other ALSEP instruments
