Supergugus ieu dipastikeun kaayaanna bulan Séptémber 2014 sabot para astronom anu diluluguan ku R. Brent Tully ti Universitas Hawaii ku cara nyiptakeun cara anyar pikeun nangtukeun supergugus, nyaéta ku cara ngukur kacepetan relatip galaksi-galaksi anu aya. Supergugus lokal anyar ieu ngagantikeun supergugus lokal saméméhna, nyaéta supergugus Virgo, anu kabukti mangrupa bagéan leutik ti supergugus Laniakea.[1][2][3][4]
