Isao Endoh, National Astronomical Observatory of Japan, reports the discovery by Shigeru Furuyama (Tone-machi, Kitasoma-gun, Ibaraki-ken, Japan) of an apparent supernova (mag 16.1) on a 20-s CCD exposure (limiting mag 17.5) taken on Nov. 21.813 UT with a 25-cm f/4.8 reflector (+ ST-9E camera). The new object is located at R.A. = 11:48:00.32, Decl. = +4:29:47.1 (equinox 2000.0; UCAC3 reference stars; Astrometrica software), which is 1".2 east and 29".9 north of the center of UGC 6771. Nothing is visible at this position on the Digitized Sky Survey. The variable was designated PSN J11480032+0429471 when it was posted at the Central Bureau's TOCP webpage and is here designated SN 2011ir based on the spectroscopic confirmation reported below. Additional CCD magnitudes for 2011ir (from unfiltered images unless otherwise noted): 1991 Jan. 23, [18.8 (DSS red plate; via Toru Yusa); Nov. 23.473, 16.6 (Yusa; remotely using a 0.25-m f/3.4 hyperbolic astrograph + SBIG ST-10XME camera at the RAS Observatory near Mayhill, NM, U.S.A.; three stacked 120-s exposures; limiting mag 18.5; position end figures 00s.29, 48".4; offset 1".3 east, 31".6 north; center of UGC 6771 at position end figures 00s.20, 16".8; USNO-B1.0 reference stars; communicated by S.
