Green; Hoffman Lab 209; Harvard University; 20 Oxford St.; Cambridge, MA 02138; U.S.A. e-mail: cbatiau@eps.harvard.edu (alternate cbat@iau.org) URL http://www.cbat.eps.harvard.edu/index.html Prepared using the Tamkin Foundation Computer Network SUPERNOVA 2010ij IN PGC 68600 Denis Vida and Filip Novoselnik, on behalf of the "La Sagra Sky Survey" (LSSS) Supernova Search Team (which includes also Luka Dukic, Ivica Skokic, Robert Gregic, David Gostinski, Salvador Sanchez, Jaime Nomen, Reiner Stoss, Bill Yeung, Juan Rodriguez and Miguel Hurtado), reports the discovery of an apparent supernova (magnitude 15.9) on three CCD images (limiting mag about 20.0) taken on Sept. 15.829, 15.843, and 15.858 UT with a 0.45-m telescope. The new object is located at R.A. = 22h20m20s.19, Decl = +17d03'22".2 (equinox 2000.0), which is 10".4 east and 4".8 south of the nucleus of the presumed host galaxy, PGC 68600. Nothing is visible at this position on a Digitized Sky Survey image from 1995 July 29.35 (red plate). An LSSS image from Sept. 15 has been posted (with the red DSS image on the right, for comparison) at website URL http://img840.imageshack.us/img840/945/image000cj.png. Vida adds that Joseph Brimacombe (Cairns, Australia) has taken an image remotely with a 32-cm RCOS telescope and (+ STL6K camera) located at the Macedon Ranges Observatory (Victoria, Australia) on Oct. 3.56, yielding mag 17.2 for 2010ij (image posted at http://img827.imageshack.us/img827/9217/pgc68600jb.png).
