Descripción
To investigate the location of the actual limit for the different
behavior, the active regions with fluxes greater than 10 to the 20 Mx
are investigated. After surveying the differences between large and
small active regions reported in the literature, the birthplaces of the
active regions are analyzed statistically. The analysis indicates that
the birthplaces of the small active regions are almost always
necessarily zones of remnant magnetic flux. This, it is noted, is in
contrast with the larger ones. The limit between the large and small
active regions is seen as approximately 10 to the 21st Mx. It is argued
that if some magnetic flux of the decaying regions is being sunk down
below the photospheric level (as suggested by numerical calculations and
some observations), then some kind of re-apparition is to be expected at
the solar surface. A tentative picture is proposed, whereby the small
active regions, and perhaps the ephemeral ones as well, are the
secondary effects after the decay of the large active regions and
complexes of activity.
