Properties of the energetic electron (E greater than or approximately equal to 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 approximately 5 with increasing geomagnetic activity, and the average unidirectional electron flux within the layer increases by a factor of approximately 4. The energy carried by electrons greater than or approximately equal to 200 keV ranges from approximately 10 to the 14th ergs per second to approximately 10 to the 15th ergs per second. Extrapolation to include all electrons greater than 1 keV suggests total energy flow ranging from approximately 3 x 10 to the 15th ergs per second at quiet times to approximately 5 x 10 to the 18th ergs per second at magnetically disturbed times.
