The evolution of sunspot group is divided into three phases: when it begin to appear on the solar surface (photosphere), when it reach its peak activity, and when if disappears. In the second phase, the sunspot group shows its activity as flares (there is reconnection between two magnetic fields) called productive phase. By observing the average daily motion of a sunspot group due to the solar rotation (approximately 13.5 deg/day) and to the activity of nearby flares, the duration of active phase of a sunspot group can be deduced. From the analyses of sunspot groups, the D, E, and F classes show a longer activity compared to other classes, supports the fact that the occurence frequency at the flares mostly produced by these classes. From the analysis we conclude that approximately 4 to 5 days after appearance of sunspot D, E, F it reach productive phase. We also obtain that the flares produced by these classes have a longer active duration compared to other classes. From the estimation of the flare-productive phase we are able to predict when a sunspot group to begin flare productive.
