Evidence for a narrow state decaying into an F meson and a photon has been obtained in e+e- annihilation events at 29-GeV c.m. energy. This state lies 139.5 ± 8.3(stat.) ± 9.7(syst.) MeV above the F-meson mass and is consistent with the expected F* meson. The F mesons are identified by a peak in the K+K-K ± mass at 1.948±0.028±0.010 GeV.
