Abstract:

Observed riometer absorption A in db is correlated with the proton spectrum variable log I 10 MeV alpha log Rho, where I10 MeV is the peak flux of protons with energies in excess of 10 MeV, Rho is a measure of the average energy of these protons and alpha is an adjustable parameter. Study of the major proton events I10 MeV 100 protons sq cm sec ster since 1967 shows excellent correlations. Even when the average energy dependent factor is ignored alpha0, our approach provides better correlations than the usual square root relation optimization over alpha further improves the correlations to r nearly equivalent to 0.97. A practical program for utilizing solar radio burst data for an early prediction of riometer absorption can now be developed by combining our previous studies on radio results from proton correlations with the proton results from riometer results reported here.
