Let $\phi_{\omega}$, $\omega \in I$, be a branch of unstable solitons of NLS whose linearized operators have one pair of simple real eigenvalues $\pm e_+(\omega)$ in addition to 0 eigenvalue. With localized perturbation to the initial data, the solution will locally either converge to the branch, or exit a neighborhood of the branch. This has implication to the blowup behavior of NLS with supercritical nonlinerity. This is a joint work with Vianney Combet and Ian Zwiers.
