Counts by Shane and Wirtanen detected a cloud of Galaxies - the Hercules Supercluster - centered at about α = 16h02m; δ = 17°00m. It is unclear whether there is a physical connection with another cloud located to the south for which no radial velocities are yet available and with the system A2197/A2199 located to the north. the latter is at slightly smaller redshift (velocities between 8000–11,000 km sec−1) than the Hercules cluster.
