Abstract:A surprisingly good correlation has been found for SPA measured at VLF propagation (Deltaphgr) and 7 GHz solar microwave burst energies (E mgr). The data are correlated in the form Deltaphgr = a log E mgr + b and include all kind of solar events, irrespectively from type, complexity or duration. Soft X-ray peak fluxes (I x) have a known similar correlation to SPA, and a functional relationship of the form 479-01 can be established. As one practical application, the energies from solar events can be reasonably well inferred from SPA data, which are quite reliable and easily obtainable.
