%X A vertex irregular total -labeling of a graph  with vertex set  and edge set  is an assignment of positive integer labels {1,2,¡­,} to both vertices and edges so that the weights calculated at vertices are distinct. The total vertex irregularity strength of , denoted by tvs() is the minimum value of the largest label  over all such irregular assignment. In this paper, we consider the total vertex irregularity strengths of disjoint union of  isomorphic sun graphs, tvs(), disjoint union of  consecutive nonisomorphic sun graphs, £¿tvs(=1
