2003IAUC.8090....2W

Further to IAUC 8089, W. M. Wood-Vasey, G. Aldering, and P. Nugent report the discovery of a supernova (mag 17.7) on unfiltered NEAT images taken with the Palomar 1.2-m Schmidt telescope on Mar. 3.48, 3.49, and 3.50 UT. The new object is located at R.A. = 10h29m44s.12, Decl. = +25o37'11".6 (equinox 2000.0), which is 0".8 west and 0".6 north of the center of the apparent host galaxy. No point source is visible at this location on Palomar images from Jan. 28.45-28.49 (limiting mag 20.1). D. A. Howell, Lawrence Berkeley National Laboratory, reports that a spectrum (range 360-900 nm) of SN 2003bs, obtained on Mar. 8.32 with the Kitt Peak 2.1-m reflector (+ GCAM), shows it to be a type-Ia supernova, approximately 1 week past peak brightness. The host galaxy is very faint, and the redshift (z = 0.05) was determined by comparison of the spectral features of the supernova to the strongly resembling features of SN 2001ay (cf. IAUC 7612).
