T. Boles, Coddenham, England, reports the discovery by Maurice Gavin (Worcester Park, Surrey, England) of an apparent supernova (mag 16.2) on an unfiltered CCD image taken on Mar. 18.924 UT with a 0.30-m reflector. The new object (measured by Boles) is located at R.A. = 12:53:53.40, Decl. = +36:05:19.6 (equinox 2000.0), which is approximately 6".6 north of the center of IC 3862. The new object was designated PSN J12535343+3605193 when posted at the Central Bureau's TOCP webpage and is here designated SN 2011az based on the spectroscopic report below.
