2012CBET.3305....1A

Ron Arbour, South Wonston, Hants, U.K., reports the discovery of an apparent supernova (mag 17.0) on unfiltered CCD images taken on Nov. 14.955 UT using a 35-cm f/6 Schmidt-Cassegrain telescope (+ SXVF-H9 camera) in the course of his supernova patrol. The new object is located at R.A. = 22:41:51.83, Decl. = +34:58:07.4 (equinox 2000.0), which is 3" east and 4" north of the center of the galaxy PGC 214858. Nothing is visible at this position on a Digitized Sky Survey Palomar blue plate from 1989 Sept. 8 or a red plate from 1988 July 11 (no limiting magnitudes provided). The variable was designated PSN J22415183+3458074 when it was posted at the Central Bureau's TOCP webpage and is here designated SN 2012go based on the spectroscopic confirmation reported below. Additional unfiltered CCD magnitudes for 2012go: 2012 Nov. 16.048, 16.7 (R. A. Koff, Bennett, CO, USA; Meade 0.25-m f/10 reflector + Apogee U-47 camera; limiting magnitude 20.0; position end figures 51s.81, 06".8; UCAC3 reference stars; image posted at URL http://antelopehillsobservatory.org/SNpictures/PSNJ22415183+3458074final.jpg); 17.850, 16.5 (D.
