Abstract:	We present an analysis of the decays B0→K0(892)γ and B+→K+(892)γ using a sample of about 383×106 B¯¯¯B events collected with the BABAR detector at the PEP-II symmetric energy B factory. We measure the branching fractions B(B0→K0γ)=(4.47±0.10±0.16)×1− 5 and B (B+→K+γ)=(4.22±0.14±0.16)×10−5. We constrain the direct CP asymmetry to be −0.033
