Time evolution of various quantities describing the sunspots and fragments in NOAA 11076. One can see the evolution of the number of detected sunspots (a) and their area (b). The cumulative curve of the splitting or merging events is also plotted (c), showing which of the quantities prevailed until the given moment. Panel d: one can see the cumulative curves of the number of objects that newly appeared and that faded staying alone. Panel e: one can see the cumulative balance between the increase and decrease in the number of objects. Finally, in (panel f), the total number of the detected objects at the given time is plotted.
