F. Manzini, Sozzago, Italy, reports his discovery of an apparent supernova (mag about 16.5) on unfiltered CCD images taken with a 0.4-m telescope on Apr. 1.87-1.91 UT, noting the new object to be 3".5 west and 3".5 south of the center of NGC 3465, and adding that nothing is visible at this location on his image from Mar. 16 (limiting mag about 19.0) or on Palomar Sky Survey images. Confirming unfiltered CCD images were obtained by Manzini, R. Crippa, and F. Fumagalli (0.4-m telescope) and by M. Amoretti (Sanremo, Italy, 0.16-m telescope) on Apr. 3.92, and by P. Holvorcem and M. Schwartz (0.81-m Tenagra telescope near Nogales, AZ) on Apr. 4.23. Holvocem reports the magnitude of SN 2004bc as 16.6 and provides the following precise position: R.A. = 10h59m31s.41, Decl. = +75o11'28".9 (equinox 2000.0), which is 4".5 west and 4".3 south of the nucleus of NGC 3465.
