STORM-TIME INCREASE OF COSMIC-RAY INTENSITY
During the period of the International Geophysical Year (July 1957- February 1958) there were several occasions in which the intensity of cosmic rays increased by a few per cent. Two typical events, which occurred on September 13, 1957, and february 11, 1958, are described. Observations indicate that the cosmic-ray intensities increased abruptly by about 2 or 3 per cent on a world- wide scale regardless of diurnal variation. Also, it was found that the increase in intensity coincided with the severest phase of magnetic storms. (J.H.M.)
