| Abstract: |
In this paper we have studied North-South (N-S) asymmetry of various solar phenomena for the period of solar cycles 6-23. The data includes sunspot data, flares (x-ray, white light, etc.) data and active prominences. The present study shows that the N-S asymmetry has a long-term period of 11 solar cycles. The study also shows that the N-S asymmetry during solar cycles 22 and 23 are southern dominated as predicted by Verma (1992). On the basis of this study we are of the view that N-S asymmetry for various solar phenomena may be southern dominated during solar cycle 24 and that the asymmetry may shift to the northern hemisphere during solar cycle 25 as suggested by Verma (1992). The result of this study may be helpful to understand long-term helioseismic phenomena and dynamo models of the Sun which are based on the magnetic fields related to solar active regions. |
