J. Newton and T. Puckett report the discovery of an apparent supernova (mag 15.6) on an unfiltered CCD frame (limiting mag 18.5) taken with a 0.40-m telescope in Portal, AZ, on Jan. 24.37 UT in the course of the Puckett Observatory Supernova Search; the new object was confirmed on frames taken on Jan. 25.34 by T. Orff (limiting mag 19.5). SN 2010O is located at R.A. = 11:28:33.86, Decl. = +58:33:51.6 (equinox 2000.0), which is 3".7 east and 5".7 north of the center of its apparent host galaxy, NGC 3690. Nothing is visible at this position on images taken by Puckett on 2009 Apr. 4 (limiting mag 19.4). The offsets of 2010O are relative to the eastern component of the interacting galaxy pair. Note that NGC 3690 is interacting with the galaxy IC 694. The discovery image has been posted at the following website URL: http://www.possdata.com/tp001.jpg.
