Özet:

 

We investigated the possible morphological variations   observed in sunspot groups on the day before flaring activity occurred   between January 1996 and November 2014. We found that 77% of all flaring   sunspot groups were large and complex (D, E, and F modified Zurich classes).   In addition, the Zurich classification of A, B, and C class sunspot groups   changed more than 50%, while the remaining groups (D, E, F, and H) did   not change considerably before the flare activity. Results showed that there   was a remarkable increase in the sunspot areas of groups D, E, and F; in   contrast, the sunspot areas of groups A, B, C, and H showed a decrease   before the flaring activity during the examined time period. Finally, the   sunspot counts of groups A, C, and H showed a decrease, while groups B, D,   E, and F showed an increase in the same period.
