2005IAUC.8530....2J

Further to IAUC 8499, C. Jacques reports the discovery of an apparent supernova (mag 15.6) by C. Colesanti, E. Pimentel, T. Napoleao and himself on unfiltered CCD images taken in the course of the Brazilian Supernovae Search on May 13.22 and 16.12 UT. SN 2005cb is located at R.A. = 19h11m21s.95, Decl. = -57o02'27".4 (equinox 2000.0), which is 16" west and 19" north of the center of NGC 6753. Nothing in visible at this location on a CCD image taken on May 2.23 (limiting mag 18.5); a faint H II region is very close to the supernova position on that image and on a red Palomar Sky Survey image from 1976.
