When (S, F, L) is a p-local finite group and (T, E, L-0) is weakly normal in (S, F, L) we show that a definition of C-S(E) given by Aschbacher has a simple interpretation from which one can deduce existence and strong closure very easily. We also appeal to a result of Gross to give a new proof that there is a unique fusion system C-F(E) on C-S(E).
