    • ...Following the observations by Wind, observations of electrons and protons in the vicinity of the Moon from other missions also suggest that a significant electric potential drop does exist across the boundary [e.g., Futaana et al., 2001; Halekas et al., 2005; Nishino et al., 2009a]...
    • ...Halekas et al. [2005] proposed a theory to explain the large potential drop by considering supra‐thermal solar wind electrons...
    • ...[19] A very simple 1D model, which is based on the classical theory of a plasma expansion into vacuum along the magnetic field line, has been employed to explain the plasma distribution in the lunar wake using an analytical formulation [Ogilvie et al., 1996; Halekas et al., 2005]...
    • ...Via =( kTe/M) 1/2 is the ion acoustic velocity under assumption (c), Ti = 0. Wind [Ogilvie et al., 1996] and Lunar Prospector [Halekas et al., 2005] observations can be better explained by assuming that the solar wind electron velocity distribution has a � distribution than by assuming a Maxwell distribution...
    • ...In particular, Lunar Prospector observations are conducted at an altitude similar to that of our observation, and the electron distributions are consistent with a model using a � distribution [Halekas et al., 2005]...

    • ...This secondary production increase may be especially relevant to kappa electron distributions, where Te increases progressively with distance from the wake flank [Halekas et al., 2005] thereby creating greater secondary production (which varies as Te)...

    • ...We also assume a Maxwellian plasma distribution describes the ambient solar wind and expansion region and future efforts could incorporate a kappa distribution [Halekas et al., 2005]...
