The radiative decay B → φKγ, which provide an important tool to search for physics beyond the standard model is observed. An upper limit for the particular decay mode and a branching fraction for the B -→φK-γ decay mode are obtained. It is found that the measured decay branching fraction is roughly an order of magnitude smaller than B→K*γ branching fractions. This factor can be attributed to the additional electron pair.
