MENDOZA-TORRES, J. E.; LUO, X. e SALAZAR, H.. The cosmic ray and the 10.7 cm flux variations during solar cycles 19-23. Rev. mex. astron. astrofis [online]. 2014, vol.50, n.2, pp.245-253. ISSN 0185-1101.
The cosmic ray flux (CRF) and 10.7 cm flux (F10.7) are studied for solar cycles 19-23. The cross-correlations show longer time-dependence at odd than at even cycles. A shift of the maximum at the histograms of CRF1 /F10.71 (the ratios of normalized values), does not depend on the polarity of the cycle. The behavior of CRF1 vs F10.71 differs for odd and even cycles and also for different cycle phases. We fitted an inverted CRF1 profile to the F10.71 profile with a linear function. The F10.71/CRFinv histogram differs for odd and even cycles. The results for sunspot number (SSN) are similar to F10.7 but differ for the F10.71 /CRFinv histograms. Summarizing, besides the differences between odd and even cycles, there occur variations at different phases of the cycles and also variations independent of the polarity of the cycle, the latter perhaps arising outside the heliosphere.
