Africa, reports his discovery of an apparent supernova (mag 15.5) on unfiltered CCD images obtained on July 30.697 and 31.692 UT at the Bronberg Observatory. The new object is located at R.A. = 12h10m38s.03, Decl. = +16d02'21".1 (equinox 2000.0), which is 7" east and 23" north of the galaxy core of NGC 4152. Nothing is visible at this position on Digitized Sky Survey images (limiting red mag 20.5) or on his previous image of this galaxy taken on July 16.690 (limiting mag 18.5).
