Properties of the energetic electron (E ≳ 200 keV) magnetopause layer along the distant magnetotail have been studied with Caltech instrumentation aboard IMP-8 for approximately 60 spacecraft orbits. The cross-sectional area of the layer appears to increase by a factor of ∼ 5 with increasing geomagnetic activity, and the average unidirectional electron flux within the layer increases by a factor of ∼ 4. The energy carried by electrons ≳ 200 keV ranges from ∼ 10^(14) ergs sec^(−1) to ∼ 10^(15) ergs sec^(−1). Extrapolation to include all electrons > 1 keV suggests total energy flow ranging from ∼ 3×10^(15) ergs sec^(−1) at quiet times to ∼ 5×10^(18) ergs sec^(−1) at magnetically disturbed times.
