\begin{abstract}
We present a study of the inclusive $D^{*\pm}$ production in the decay
of $\Upsilon(1S)$ using $(98.6 \pm 0.9)\times 10^6$ $\Upsilon(2S)$
mesons collected with the
\mbox{\slshape B\kern-0.1em{\smaller A}\kern-0.1em
B\kern-0.1em{\smaller A\kern-0.2em R}}
detector at the $\Upsilon(2S)$
resonance. Using the decay chain $\Upsilon(2S)\to \pi^+ \pi^- \Upsilon(1S),\;
\Upsilon(1S) \to D^{*\pm} X$, where $X$ is unobserved, we measure the
branching fraction $\BR[\Upsilon(1S)\to D^{*\pm} X] = (2.52 \pm
0.13({\rm stat}) \pm 0.15({\rm syst}))\%$ and the $D^{*\pm}$ momentum
distribution in the rest frame of the $\Upsilon(1S)$. We find evidence for an
excess of $D^{*\pm}$ production over the expected rate from the
virtual photon annihilation process $\Upsilon(1S)\to\gamma^*\to c\bar c\to
D^{*\pm} X$.
