All the available nightside electron data obtained during circular orbits at Mars from the Phobos‐2 HARP instrument have been examined in detail and are summarized in this paper. An electron flux component with energies exceeding that of the unperturbed solar wind was observed inside the magnetosheath, indicating the presence of acceleration mechanism(s). The character of the electron fluxes measured in the magnetotail cannot be classified in any simple manner; however, there is a correlation between the electron fluxes measured well inside this region and the unperturbed solar wind ram pressure.
