A statistical analysis of soft X-ray effects in the low terrestrial ionosphere and some inferences on the nature of solar flares.
Abstract
Magnitudes corresponding to solar flare soft X-ray mean fluxes and energies can be derived from phase anomalies produced in lower ionosphere VLF propagation, producing a homogeneous set of data (500 events). The statistical analysis of a large collection of events indicates that they might behave as the integrated response to a quantisable phenomenon. A characteristic frequency can be tentatively assigned to every event, of which the corresponding total energy would be a multiple of an elementary magnitude that could be statistically estimated. This concept may be reconciled with recent hard X-ray on solar flares and with characteristic Alfven parameters associated with flaring centers.
