Solar flare effects on cosmic ray intensity

A note on solar flare cosmic rays

“…An apparent contradiction exists among their conclusions. This brief note is intended to point out a possible interpretation for these discrepancies in terms of the selection of data used in their analyses.According to the Chree analysis done by Towle and Lockwood [1959], and Ghielmetti, Anderson, Cardoso, Manzano, Roedeter, and Santochi [1960], no significant increase in cosmicray intensity with solar flares is detected during the period from 1956 to 1957, and from July 1957 to August 1958, respectively. on the other hand, Kolomeets [1959] found significant increases at four stations in Europe for the period of several months in 1957.In all three analyses, the intensity of cosmicray neutrons corrected for barometric pressure is used; the only essential difference between the former and the latter is the consideration on impact zones' namely, Towle-Lockwood and Ghielmetti and his co-workers have restricted their analyses to events in the impact zones, but Kolomeets did not.…”
