Measurements of precipitating electrons with E400 kev were made from 25 February to 10 March 1965 with a solid-state detector aboard a near polar satellite at altitudes from 170 to 220 km. Auroral zone data were taken 3.5 or L or 7.5 in two longitude intervals 170 degrees E to 225 degrees E and 278 degrees E to 300 degrees E. During every auroral zone pass a flux of electrons, E 400 kev, was observed ranging from 1000 electrons to 100,000 electronssq cm-sec, while at other latitudes the maximum flux observed was less than 150 electronssq cm-sec. For the 278 degrees to 300 degrees longitude interval the conjugate points were mostly below 100 km. Fine temporal or spatial variations were observed during one pass the flux changed by up to a factor of five in a few tenths of a second. Author
