The Southern Supercluster Strand is a galaxy filament that incompasses the Southern Supercluster and the Telescopium−Grus Cloud.[1]

In 2014, it was announced that the Southern Supercluster Strand is a lobe in a greater supercluster, Laniakea, that is centered on the Great Attractor.[2] This would mean that the Southern Supercluster Strand's components, the Telescopium−Grus Cloud and the Southern Supercluster[1] would be part of this new supercluster. The Virgo Supercluster would also be part of this greater supercluster, thus becoming the local supercluster.[2]
