“…and cooling rates have been calculated in the manner described above and reasonable agreement between the two rates has been reported for the daytime ionosphere [Brace et al, 1969;Spencer et al, 1965;Pharo et al, 1971;Timothy et al, 1972;Klyueva et al, 1972].…”

“…This data set was the only one found that provides solar flux values below 30 • and simultaneously overlaps the AFGL data in the work by Heroux [Van Tassel et al, 1981]. Although only line intensities were reported, we have summed them in 10 3, intervals and normalized them to the AFGL data to construct the composite spectrum below 50 3,.…”

In the present work we have used the best available solar spectral data together with our absolute neon ionization cell data to estimate the absolute solar soft X ray flux and its variation with solar activity in the 20‐ to 100‐Å region. Since the neon chamber data cover the integral spectral region from 20 to 575 Å we have constructed a composite spectrum covering that region so that the fraction of solar flux in the 20‐ to 100‐Å region could be determined. Both sounding rocket and satellite observations obtained over the past two decades have been used in the present analysis. Most of these prior data were acquired during low and moderate solar activity levels in contrast with the neon ionization cell data which were obtained during moderate and maximum solar activity levels. Based on these combined data sets we have shown the dependence of the integrated solar soft X ray flux between 20 and 100 Å on the daily 10.7 cm radio flux observed at 1 AU and have obtained an estimate of the maximum flux that can be expected over the solar cycle.

“…InFigure 3the results of the calculation are presented. A theoretical inelastic loss function[Timothy et al, 1972] and e-e elastic loss function[Schunk and Hays, 1971] are also shown for the same' altitude.Calculations and theory are in reasonable agreement between 7 and 17 V. Above 17 V the degraded primaries must be contributing to the flux. However, since their production function is different from that of the secondaries, a departure from theory is expected.…”

A measurement of the low‐energy auroral electron flux distribution between 0.5 and 80 eV reveals structure between 0.5 and 10.0 eV. The structure is due to the thermal electron Maxwellian distribution and electron energy loss to thermal electrons, molecular nitrogen, and atomic oxygen. Some physical process in the auroral plasma causes the deduced loss function to differ from theory. Reasonable agreement is obtained between calculated and measured N2 second positive emission.
