This can be identified with what we now know as the core of the Shapley Supercluster. Shapley estimated the distance to this cloud to be 14 times that to the Virgo Cluster, from the average diameters of the galaxies.
The object in question is the central part of the Shapley Supercluster.  Shapley determined the distance to this cloud to be 14 times greater than the distance to the Virgo Cluster, using the average diameter of the galaxies as a reference point.
