The 27-day variation in cosmic ray intensity
The study of electromagnetic phenomena like magnetic storms. aurorae, and certain types of cosmic-ray effects like the 27-day variation in intensity is of impontance for the proper understanding of the interplanetary electromagnetic state. Since solar activity appears to influence the electromagnetic conditions in interplanetary space. changes in solar activity during its eleven-year cycle would be revealed in the above effects. The relation between the transient behavior of the geomagnetic field and cosmic-ray intensity appears to be definitely established. Graphical data indicate that the amplitude of the 27-day variation in cosmic-ray intensity is more closely connected with geomagnetic activity than with solar activity. (A.C.)
