The intersection of a sun $M$ in $C(Q)$ with a closed span $\Pi\subset C(Q) $ (in particular, with a closed ball) is shown to be a strict protosun, provided that the natural condition $M\cap\operatorname{int}\Pi\ne\varnothing$ is satisfied. This property is shown to characterize closed spans in $C(Q)$.
