Zhangwei Jin (Ningbo, Zhejiang, China) and Xing Gao (Urumqi, Xinjiang, China) report the discovery of an apparent supernova (mag approximately 17.3) near the galaxy NGC 6246A = PGC 59090 on a 60-s survey image (limiting mag about 19.0) taken by Xing Gao in the course of the Xingming Observation Sky Survey around Feb. 18.922 UT using an unfiltered CCD with a Celestron C14 0.35-m Schmidt-Cassegrain telescope at Mt. Nanshan. The new object, which was designated PSN J16501398+5522280 when posted on the Central Bureau's TOCP webpage and is here designated SN 2011aj (based on the spectroscopy reported below), is located at R.A. = 16:50:13.98, Decl.= +55:22:28.0 (equinox 2000.0). Additional approximate magnitudes (unfiltered CCD unless noted otherwise): 1992 June 29, [19.5 (Digitized Sky Survey; via Jin and Gao); 2011 Feb. 16.924, 17.7 (Jin and Gao); 22.397, 16.6 (J. Brimacombe, Cairns, Australia; remotely using a robotic 0.51-m RCOS telescope + SBIG STL11K CCD camera near Mayhill, NM, U.S.A.; position end figures 14s.01, 28".5).
