Abstract
The rocket with the experiment was fired from Fort Churchill, Canada, over a homogeneous arc at 2000 local time on Feb. 26, 1969. Detectors measured the pitch-angle distribution of the fluxes of electrons with energies in the range from 2 to 18 and energies above 50 keV, and of protons with energies in the range from 2 to 18 and in the range from 80 to 1000 keV. The total backscattered flux was about 20% of the downward flux in the same energy range. No protons in the range from 2 to 18 keV, or any higher energy particles, were found in significant quantities. It was found that the energetic auroral electrons carry a substantial part of the Birkeland current. The arc extended at least 1500 km in an east-west direction and was not associated with substorm activity.
