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).
