T. Boles, Coddenham, England, reports the discovery of an apparent supernova (mag 18.0) on an unfiltered CCD image taken on July 31.071 UT with a 0.35-m reflector. The new object is located at R.A. = 1:26:34.69, Decl. = +31:37:03.6 (equinox 2000.0, presumed), which is approximately 14".2 east and 5".1 north of the center of MCG +05-4-59 = PGC 5364. The variable was designated PSN J01263469+3137036 when it was posted at the Central Bureau's TOCP webpage and is here designated SN 2011ix based on the spectroscopic confirmation reported below.
