Allowing for the relative tilt of the cluster to the border, the closest point to the Norma border is roughly 16h 15m, -60 30, the furthest point roughly 16h 17m, -61 30'. My calculations put the closest point roughly 15 arcminutes form the Norma/Tra border and the furthest point about 75 arcminutes from the border.
According to this, no part of the cluster is in Norma. At least not on current boundaries.
