Description
There are different mechanisms affecting the formation of
sunspot groups e.g. buoyancy on the emerging flux ropes,
drag force, tension, etc. To check the roles of these
theoretical mechanisms one needs to study the evolutionary
phases of sunspots and sunspot groups on a large statistical
sample. Our study is based on the SOHO/MDI – Debrecen Data
(SDD). Its high-temporal resolution allows to study the
emergence and decay of the sunspot groups in detail. We
investigate the distance and the growth/decay rates as well
as the asymmetry between the compactness of the different
polarity parts of active regions in time.
