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).
