SN 2001bb
M. Schwartz, on behalf of LOTOSS collaboration (Mike and KAIT),
discovered SN 2001bb on Apr 29.3 (mag about 16.5) and confirmed one
day later when SN became mag 0.2 brighter. The position is about
16".8 west and 1".4 south of the nucleus of the tilted spiral galaxy
IC 4319. The expected maximum of the typical SN Ia on this galaxy
is about 15.6, and it seems that SN 2001bb was discovered in its
rising phase
(vsnet-campaign-sn 172).
IAUC 7616 informed that the spectra of SN 2001bb have been taken
by Lick and KPNO, which reveal that it is of type I SN
(vsnet-campaign-sn 173).
