In this work, we tried to predict the parameters of Bc∗ meson. Simple assumptions gave us the following parameters mBc∗ =6329±10MeV and fBc∗ =535.5±57.8MeV (for ΛBc∗ = 2.26±0.14GeV in covariant confined quark model). We calculated widths of radiative decays of B∗q mesons, where q=u/d,s,c and compared them with other theoretical works. It was shown that the width of the Bc∗ meson is very sensitive to the mass mBc∗ as expected and less to the size parameter ΛBc∗.
