A Note on the Unusual Variations of Cosmic Ray Intensity During the Period 1960 November 10 to 16

Abstract

An unusual sequence of cosmic ray variations, observed in London in connection with the high level of solar and geophysical activity prevailing during the period 1960 November 10–16, is described. The results are compared with cosmic ray observations made elsewhere and with other relevant geophysical phenomena. Some of the features encountered are unique in the type of event considered, and the implications of these results are briefly discussed.
