Description

Nearly 1000 solar events with fluxes measured in 0.5-3A0, 1-8A0 and 8-20A0 bands by Explorer 37 (US NRL Solrad) satelite are statistically analysed. The differential distribution of peak fluxes can be represented by power laws with exponents -1.4, -2.2, -2.9 respectively, which are compared to 2-12A0 results. At the 0.5-3A0 band there is a suggested peak in the distribution. Autocorrelation analysis of the distribution have shown that in the harder band (0.5-3A0) there is a concentration of events at preferred values multiplied of about 10x10-5erg cm-2S-1 of unknown origin

Abstract (Portuguese)

Analisam-se cerca de 1000 eventos solares com fluxos medidos pelo satelite Explorer 37 (US NRL Solrad) nas bandas 0.5-3A0, 1-8A0 e 8-20A0. As distribuicoes diferenciais dos fluxos maximos nas tres bandas podem ser representadas por leis de potencia cujos expoentes sao -1.4, -2.2, e-2.9 respectivamente, os quais sao comparados com resultados obtidos na banda 2-12A0. Para os dados na banda de 0.5-3A0 sugere-se a existencia de um pico na distribuicao. A partir de uma analise por autocorrelacao da distribuicao encontrou-se na banda mais dura (0.5-3A0) uma tendencia de concentracao de eventos em valores multiplos de cerca de 10x10-5erg cm-2S-1 cuja origem e desconhecida
