Description

The timeline of solar activity is discussed with data for the annual mean north-south excess (NSE) of hemispheric sunspot numbers (SSNs) for 1945-2014, covering five SSN cycles (18-23) and the rising phase of cycle 24. We report the results of our study of the relation between NSE and galactic cosmic ray (GCR) modulation at 1 a.u. The significance of our results is discussed.
