On supercyclicity of operators from a supercyclic semigroup

We show that for every supercyclic strongly continuous operator<br/>semigroup $\{T_t\}_{t\geq 0}$ acting on a complex $\F$-space, every<br/>$T_t$ with $t>0$ is supercyclic. Moreover, the set of supercyclic<br/>vectors of $T_t$ does not depend on the choice of $t>0$.
