Here the author analyzes data collected from the Dynamics Explorer satellites DE-1 and DE-2 to interpret observations of electron conics. DE-1 was at altitudes around 10,000 km over the auroral oval, while DE-2 was at an altitude of roughly 1000 km in the same latitude and local time. The author compares the observations made from both platforms of the distribution functions of electron conics and beams seen in their environments. The DE-2 observations occasionally show a broadly spread electron beam accelerated downward, wihin a pitch angle of about 55{degrees}, and a conic distribution propagating upward with a similar pitch angle. The latter is interpreted as the mirroring of downward beam electrons which fall in the loss cone.
