We have compiled a catalog of activity complexes (AC) in cycle 24 and revealed the main parameters of AC evolution inthe cycle. A total of 118 ACs were identied in cycle 24. New ACs occur mostly near the existing ACs. From cycle 21 to24, the north-south asymmetry in AC spatial distribution increases, and the power of AC decreases monotonically. Thereare coronal holes near all the ACs. About 80% of all M- and X-class X-ray ares occurred in ACs.
