We have measured the inclusive bsγ branching ratio to be (2.32±0.57±0.35)×10-4, where the first error is statistical and the second is systematic. Upper and lower limits on the branching ratio, each at 95% C.L., are B(bsγ)<4.2×10-4 and B(bsγ)>1.0×10-4. These limits restrict the parameters of extensions of the standard model.
