Active latitudes for sunspot occurrences in the Solar Cycle 23 View all abstracts by submitter

Valentina Zharkova   Submitted: 2010-02-16 08:12

In this paper we carry out the principal component analysis of the sunspot and background magnetic fields in the cycle 23. There two main latitude pe- riodical components of the opposite polarities derived in sunspot magnetic flux which behave rather off-phase in the Northern and Southern hemispheres. These waves are shown to be modulated by the two primary waves of the back- ground magnetic field which have the opposite polarities and travel slightly off-phase in each hemisphere. In the cycle 23 the maximums in sunspot components correspond to the minimums in the BMF components. This points out to a presence of the two waves in BMF travelling in each hemisphere (possibly, in the opposite directions or having the opposite polarities) which affect the sunspot appearances in these hemispheres.
