  We associate to each nilpotent orbit of a real semisimple Lie algebra $g_o$ a
weighted Vogan diagram, that is a Dynkin diagram with an involution of the
diagram, a subset of painted nodes and a weight for each node. Every nilpotent
element of $g_o$ is noticed in some subalgebra of $g_o$. In this paper we
characterize the weighted Vogan diagrams associated to orbits of noticed
nilpotent elements.
