SN 2002jj
IC 340, a host galaxy of SN 2002jj is a lenticular galaxy. The expected
maximum for typical SN Ia is mag about 15.6. Lenticular galaxies are believed
to produce SNe Ia only. On the other hand, the reported magnitudes (16.5mag)
suggest that it does not like SN Ia but it can be of type IIP in the plateau
phase, though it seems somewhat brighter than typical SNe II (vsnet-campaign-sn
513). This SN was turned out to be a type Ic SN, about one month after
maximum on Dec. 12. Such a evolution of the light curve observed in this
supernova is quite exceptional for type Ic SN (vsnet-campaign-sn
519).
