Study of magnetic flux emergence and related activity in active region NOAA 10314
We study the extremely complex active region (AR) NOAA 10314, that was observed from March 13-19, 2003. This AR was the source of several energetic events, among them two major (X class) flares, along a few days. We follow the evolution of this AR since the very first stages of its emergence. From t...
