SN 2001cz : Possible overluminous supernova?

IAUC 7657 informed that R. Chassagne discovered SN 2001cz at mag 14.7. on July 4. The position is about 1" west and 32" south of the nucleus of the tilted spiral galaxy NGC 4679. NGC 4679 is one of the brightest member of the Centaurus Cluster ACO 3526. This cluster has a large velocity dispersion, which is probably due to the ongoing dynamical phenomena such as cluster merging. The recession velocity of the cluster as a total is about 3400 km/s, which indicate that the expected maximum of typical SN Ia is around mag 15.0 (vsnet-campaign-sn 210).
