The observation of flaring sunspots group (active region) has been conducted to obtain the characteristic of spot's motion. In active region NOAA 0375 the motion is divided in two periods, 3-8 June 2005, when the group was growing, and 10-12 June 2003 when it was decaying. By comparing the movement plots, we see that the strong flares were most produced when the active region was in the decaying phase.
