We investigate the violent events in the cluster of two active regions (ARs), NOAA numbers 11121 and 11123, observed on 11 November 2010 by the Solar Dynamics Observatory (SDO). Within one day the magnetic eld intensity increased by 70% with the emergence of new groups of bipoles in AR 11123, where three laments are seen along the complex inversion line. The destabilization of the laments led to ares and CMEs. The CMEs around 08:24 UT and 17:00 UT are directly related to the partial eruption of one lament in the new AR, as shown by a topology computation and analysis. The other CMEs on this day are due to either other AR or to the destabilization of the global magnetic conguration of the two ARs. This conclusion can be only reached by using the three eyes of SOHO, STEREO and SDO.
