A NEW METHOD FOR NORTH-SOUTH ASYMMETRY OF SUN SPOT AREA ANALYSIS
We have studied the temporal variation in the North-South asymmetry of the sunspot area during the period from 1874 to 2007. Though the 9-year periodicity is commonly reported, shorter periodicities is still under study. We employ the cepstrum analysis method to analyze the noisy power spectrum of t...
