NASA/ADS
Abstract
R. Evans, Hazelbrook, N.S.W., reports his visual discovery with a 0.31-m reflector of an apparent supernova (mag about 13.2) on June 12.82 UT, located on top of the southern spiral arm of the galaxy, 20" east and 150" south of the center of M74 = NGC 628. R. H. McNaught, Australian National University, reports confirmation of the new object (red mag 13.9) on images taken on June 13.84 with the 1.0-m telescope at Siding Spring Observatory, with a precise position measured as R.A. = 1h36m42s.65, Decl. = +15o44'20".9 (equinox 2000.0; poor fit with about 50 USNO-A2.0 stars; uncertainties +/- 0".6 in R.A., +/- 0".3 in Decl.), which is 13".2 east and 161" south of the center of M74. A foreground star of red mag 12.4 has position end figures 32s.00, 45'08".7. McNaught adds that SN 2003gd is absent from Digitized Sky Survey images.
