D. Rich, Hampden, ME, USA, reports his discovery of an apparent supernova (mag about 18.0) on unfiltered CCD frames (limiting mag 19.0) taken with a 0.41-m reflector on May 27.086 UT, with a confirming image obtained on June 1.109 (mag about 17.6). The new object is located at R.A. = 15:31:57.65, Decl. = +68:14:42.8 (equinox 2000.0), which is about 17".6 west and 4".0 south of the center of IC 1129. Nothing is visible at this position on a CCD frame taken by Rich on Apr. 26.131 (limiting mag about 19.0) or on Palomar Digital Sky Survey images from 1991 June 8 (limiting red mag about 20.5) and 1991 May 16 (limiting blue mag about 21.0). The variable was designated PSN J15315765+6814428 when it was posted at the Central Bureau's TOCP webpage and is here designated SN 2012cs based on the spectroscopic confirmation reported below. Additional CCD magnitudes for 2012cs: June 1.370, 17.6 (L. Elenin, Lyubertsy, Russia; and I. Molotov, Moscow, Russia; stacked images remotely taken at the ISON-NM Observatory near Mayhill, NM, USA, with a 0.45-m f/2.8 telescope; position end figures 57s.65 ± 0".12, 42".7 ± 0".11; reference stars from NOMAD catalogue; limiting mag abaout 19.8; image posted at website URL http://spaceobs.org/images/TOCP/PSNJ15315765+6814428-20120601.png); 2.421, 17.7 (Joseph Brimacombe, Cairns, Australia; remotely using a 51-cm RCOS telescope + STL11K camera at the New Mexico Skies Observatory near Mayhill; luminance filter; position end figures 57s.66, 42".1; image posted at URL http://www.flickr.com/photos/43846774@N02/7331003718/). The type-Ia supernova 2003K also appeared in IC 1129 (cf. IAUC 8048).
