The first satellite observations of the total field-aligned component of the quasi-dc Poynting flux are presented, along with energy input due to electron precipitation, for two passes over the polar region, one in the noon sector and one in the afternoon. In the noon pass, the downward Poynting flux in the auroral oval was comparable to the kinetic energy input rate. The peak electromagnetic energy input rate of 6 ergs/sq cm-s equaled the peak particle input while the integrated electromagnetic value along the trajectory was 60 percent that of the particles. In the afternoon pass, the peak electromagnetic energy input was also about 6 ergs/(sq cm-s) but the peak particle energy was six times this value. The average electromagneic input was 10 percent of the particle input for the pass. Both passes show small regions characterized by upward Poynting flux suggesting a neutral wind dynamo.
