Li reports the LOSS discovery of an apparent supernova (mag 14.8) on unfiltered KAIT images taken on Nov. 27.4 UT. SN 2003kf is located at R.A. = 6h04m35s.42, Decl. = -12o37'42".8 (equinox 2000.0), which is 9".2 east and 14".3 south of the center of MCG -02-16-2. Following requests from the Central Bureau, confirmation was obtained on unfiltered CCD images by M. Armstrong (Rolvenden, Kent, England; 0.35-m reflector; mag 14.3 on Nov. 28.022; position end figures 35s.47, 42".5) and by K. Itagaki (Teppo-cho, Yamagata, Japan; 0.60-m reflector; mag 15.7 on Nov. 28.540; position end figures 35s.46, 42".5; communicated via S. Nakano, Sumoto, Japan). T. Matheson, P. Challis, and R. Kirshner, Harvard-Smithsonian Center for Astrophysics, report that a spectrum (range 320-880 nm) of SN 2003kf, obtained by Matheson on Nov. 28.29 UT with the Baade 6.5-m Magellan telescope (+ IMACS spectrograph), shows it to be a type-Ia supernova near maximum. Adopting the NASA/IPAC Extragalactic Database recession velocity of 2215 km/s for the host galaxy, the supernova expansion velocity is 12600 km/s for Si II (rest 635.5 nm).
