Supernova 1986G in NGC 5128
Abstract
R. Evans, Hazelbrook, N.S.W., reports his discovery on May 3.5 UT of a supernova of mag 12.5 and located 120" east and 60" south of the nucleus of NGC 5128 = Cen A. T. Cragg provides the following precise position, obtained directly with the Anglo- Australian Telescope, and notes that the object is in a dark lane: R.A. = 13h22m40s5, Decl. = -42deg46'16" (equinox 1950.0). Measurements by R. H. McNaught of an exposure by C. Humphries with the U.K. Schmidt Telescope on May 3.605 UT gave end-figures 40s45, 18"7 ( uncertainty 0"7) and magnitude B = 13.23 +/- 0.11. Visual magnitude estimates by McNaught gave: May 3.545 UT, 12.4; 3.589, 12.5; 4.507 13.0; 4.654, 12.4. Evans confirms that the object was fainter (mag 13.0) on May 4.50 UT.
