Further studies of cosmic ray bursts with solar activity

Abstract

Among the upper air observations of cosmic ray intensity, Pomerantz after a preliminary choice selected nine instances to relate them to solar flares, giving corresponding radio data and reproducing the cosmic ray records. As these were events described in some detail, it was considered desirable to examine them with reference to the evolution of corresponding solar active regions. As evolution of the region was considered, the use of available solar magnetic data previous and subsequent to the actual flares would be unobjectionable. Solar magnetic data were also available for one of the five very large solar flares connected with cosmic ray bursts and allowed good comparision. The examination has not indicated any modification of the conclusions drawn earlier.
