Abstract
A diurnal variation has been observed at 1000 km in the outer radiation zone in the average intensity of trapped electrons with energies greater than 40 kev and in the average intensity and frequency of occurrence of precipitated electrons of the same energy. The amplitude of the variation is greatest near the high-latitude boundary of the outer zone, but extends down to invariant latitudes of λ = 60° (L ~ 4.5). In the latitude range λ = 60° to 68° the shape of the distributions of average intensity against local time is very similar for both the trapped and precipitated electrons with the daily maximum occurring around 0800 hours local time. Good statistical agreement is obtained between the frequency of occurrence of precipitation and auroral absorption at two different local times.
