Monard, Pretoria, South Africa, reports his discovery of an apparent supernova (mag 15.8) on unfiltered CCD images taken on July 2.690 and 3.700 UT. The new object is located at R.A. = 11h20m16s.96, Decl. = +12d58'46".6 (equinox 2000.0), which is 28" east and 42" south of the galaxy core of M66 = NGC 3627. Nothing is visible at this position on Digitized Sky Survey images (limiting red mag 20.5) or on Monard's most recent previous image of this galaxy taken at his Bronberg Observatory on June 15.707 (limiting mag 18.5).
