Resumen:
During the rising phase of Solar Cycle 24, tremendous magnetic solar activity occurs on the
Sun with fast and compact emergence of magnetic ux leading to burts of ares (C to M
and even X class) . We have investigated the violent events occuring in the cluster of two
active regions AR 11121 and AR11123 observed in November by SDO. In less than two days
the magnetic eld increases by a factor of 10 with the emergence of groups of bipoles. A
topology analysis demonstrates the formation of multiple separatrices and quasi-separatrix
layers explaining possible mechanisms for destabilization of the magnetic structures such as
laments and coronal loops.
