T. Matheson, P. Challis, and R. Kirshner, Harvard-Smithsonian Center for Astrophysics, report that a spectrum (range 370-750 nm) of SN 2004C, obtained by P. Berlind on Jan. 15.51 UT with the F. L. Whipple Observatory 1.5-m telescope (+ FAST spectrograph), shows it to be a type-Ic supernova, similar to SN 1990U about three weeks past maximum (see Matheson et al. 2001, A.J. 121, 1648). The spectrum is highly reddened and shows a strong, narrow Na I D absorption at the velocity of the host galaxy with an equivalent width of 0.3 nm. The dust maps of Schlegel et al. (1998, Ap.J., 500, 525) indicate a low value for Galactic reddening of E(B-V) = 0.015.
