Formation of active regions on the rising slope of the 23rd Solar activity cycle and the law of surface distribution for Solar active regions
Abstract
We studied the topology of generation of 91 sunspot groups on the photosphere level in the beginning of the 23rd cycle of solar activity (1997-1999) and its connection to the solar background field structure. The study of distribution of sunspot groups at the solar surface in relation to wide scale background field structure provided us with one more proof of their non-Poisson distribution, which leads us the idea that generation of active regions on the Sun's surface is not an accidental and rare event. The sunspot generated at the edge of active region caused serious changes in their structure. During the 23rd cycle of solar activity the activity cycle moved from the southern to northern hemisphere.
