Unidirectional anisotropies in the energetic electron fluxes (E ≳ 200 keV) have been observed in the earth's magnetotail with the Caltech Electron/Isotope Spectrometer on IMP‐8. The anisotropies occur during periods of enhanced fluxes and provide essential information on the topology (open or closed) of the magnetotail field lines which are associated with recently identified acceleration regions.
