Why is the Norma Cluster not in Norma?
Hi All,
I've been doing some reading on the Great Attractor and also on dark flow.
The Norma Cluster (Abell 3627) is associated with the Great Attractor.
In trying to locate its position from its coordinates, I realised the Cluster is not in fact in Norma but in Triangulum Australe.
Wikipedia gives the co-ordinates of Abell 3627 as 16h 15m 32.8s, -60 54' 30" and indicates the cluster is in Norma.
SIMBAD gives the coordinates as 16 14 22.5, -60 52 07 which is not far off that given in wikipedia.
Curiously, wikipedia states the spiral galaxy ESO 137-001 is located in Abell 3627 (Norma Cluster) but indicates it is in Triangulum Australe.
So, why is the Norma Cluster not in Norma but in Triangulum Australe?
Regards, Rob
