Abstract: In certain classes of subharmonic functions $u$on $\mathbb C$ distinguished in terms of lower bounds for the Riesz measure of $u$, a sharp estimate is obtained for the rate of approximation by functions of the form $\log \vert f(z)\vert$, where $f$ is an entire function. The results complement and generalize those recently obtained by Lyubarskii and Malinnikova.
