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 ~1014 ergs sec-1 to ~1015 ergs sec-1. Extrapolation to include all electrons >1 keV suggests total energy flow ranging from ~3¿1015 ergs sec-1 at quiet times to ~5¿1018 ergs sec-1 at magnetically disturbed times.
