Analysis of charm quark fragmentation at 10.5 GeV, based on a data sample of 103 fb collected by the CLEO experiment. Fragmentation into charm is studied for the charmed hadron ground states, namely $D^0$, $D^+$, as well as the excited states $D^{*0}$ and $D^{*+}$. This analysis can be used to constrain charm fragmentation in Monte Carlo generators.
