The light cone sum rules method is used in studying the radiative decays$\Sigma_Q \to \Lambda_Q \gamma$ and $\Xi^\prime_Q \to \Xi_Q \gamma$. Firstly,the sum rules for the form factor $F_2(Q^2=0)$ responsible for thesetransitions is constructed. Using this result the decay widths of theabove--mentioned decays are calculated and analyzed. A comparison of ourpredictions on the decay widths of considered transitions with the predictionsof the other approaches is presented.
