This SN was discovered by LOSS
(IAUC 8443) on November 17, 2004, and absent on Novenber 14, 2004,
so discovered rather young. Also, reported to be rising.
The host galaxy
is at z=0.016128 (NED).
Early photometry by Li et al. may indicate type Ib/c. Later confirmed
by Keck spectroscopy by Filippenko et al.
