Query: What is the role of the meson cloud in the $\Sigma^{*0} \to \gamma
  \Lambda$ and $\Sigma^\ast \to \gamma \Sigma$ decays?   We study the effect of the meson cloud dressing in the octet baryon to
decuplet baryon electromagnetic transitions. Combining the valence quark
contributions from the covariant spectator quark model with those of the meson
cloud estimated based on the flavor SU(3) cloudy bag model, we calculate the
transition magnetic form factors at $Q^2=0$ ($Q^2=-q^2$ and $q$ the
four-momentum transfer), and also the decuplet baryon electromagnetic decay
widths. The result for the $\gamma^\ast \Lambda \to \Sigma^{\ast 0}$ decay
width is in complete agreement with the data, while that for the $\gamma^\ast
\Sigma^+ \to \Sigma^{\ast +}$ is underestimated the data by 1.4 standard
deviations. This achievement may be regarded as a significant advance in the
present theoretical situation.
