SUPERNOVA 2003kc IN MCG +05-23-37
Further to IAUC 8241, J. Burket and W. Li report the LOSS discovery, on unfiltered KAIT images taken on Nov. 21.6 (mag about 18.8) and 22.6 UT (mag about 18.1), of a supernova located at R.A. = 9h46m34s.32, Decl. = +30o39'19".0 (equinox 2000.0), which is 5".4 west and 8".2 north of the nucleus of MCG +05-23-37. A KAIT image taken on Apr. 2.2 showed nothing at this position (limiting mag about 19.5). R. J. Foley, B. J. Swift, and A. V. Filippenko, University of California, Berkeley, report that inspection of CCD spectra (range 330-1000 nm), obtained on Nov. 22 UT with the Shane 3-m telescope at Lick Observatory, reveals that SN 2003kc is of type Ia, similar to SN 1991T (Filippenko et al. 1992, Ap.J. 384, L15). Strong Fe III features suggest that it is near maximum brightness.-----------------------------
