Abstract : The effects of 4 keV protons on the earth's upper atmosphere at mid-latitudes have been investigated. A Monte Carlo calculation of the flux distribution in the atmosphere, assuming that the initially monoenergetic protons are uniformly mirroring at altitudes where neutralization is important, shows that two-thirds of the incident protons are lost to space and none penetrate to altitudes lower than 135 km.
